-This file documents changes in the firmware-only USB driver for atmel's AVR
-microcontrollers. New entries are always appended to the end of the file.
-Scroll down to the bottom to see the most recent changes.
-
-2005-04-01:
-  - Implemented endpoint 1 as interrupt-in endpoint.
-  - Moved all configuration options to usbconfig.h which is not part of the
-    driver.
-  - Changed interface for usbVendorSetup().
-  - Fixed compatibility with ATMega8 device.
-  - Various minor optimizations.
-
-2005-04-11:
-  - Changed interface to application: Use usbFunctionSetup(), usbFunctionRead()
-    and usbFunctionWrite() now. Added configuration options to choose which
-    of these functions to compile in.
-  - Assembler module delivers receive data non-inverted now.
-  - Made register and bit names compatible with more AVR devices.
-
-2005-05-03:
-  - Allow address of usbRxBuf on any memory page as long as the buffer does
-    not cross 256 byte page boundaries.
-  - Better device compatibility: works with Mega88 now.
-  - Code optimization in debugging module.
-  - Documentation updates.
-
-2006-01-02:
-  - Added (free) default Vendor- and Product-IDs bought from voti.nl.
-  - Added USBID-License.txt file which defines the rules for using the free
-    shared VID/PID pair.
-  - Added Readme.txt to the usbdrv directory which clarifies administrative
-    issues.
-
-2006-01-25:
-  - Added "configured state" to become more standards compliant.
-  - Added "HALT" state for interrupt endpoint.
-  - Driver passes the "USB Command Verifier" test from usb.org now.
-  - Made "serial number" a configuration option.
-  - Minor optimizations, we now recommend compiler option "-Os" for best
-    results.
-  - Added a version number to usbdrv.h
-
-2006-02-03:
-  - New configuration variable USB_BUFFER_SECTION for the memory section where
-    the USB rx buffer will go. This defaults to ".bss" if not defined. Since
-    this buffer MUST NOT cross 256 byte pages (not even touch a page at the
-    end), the user may want to pass a linker option similar to
-    "-Wl,--section-start=.mybuffer=0x800060".
-  - Provide structure for usbRequest_t.
-  - New defines for USB constants.
-  - Prepared for HID implementations.
-  - Increased data size limit for interrupt transfers to 8 bytes.
-  - New macro usbInterruptIsReady() to query interrupt buffer state.
-
-2006-02-18:
-  - Ensure that the data token which is sent as an ack to an OUT transfer is
-    always zero sized. This fixes a bug where the host reports an error after
-    sending an out transfer to the device, although all data arrived at the
-    device.
-  - Updated docs in usbdrv.h to reflect changed API in usbFunctionWrite().
-
-* Release 2006-02-20
-
-  - Give a compiler warning when compiling with debugging turned on.
-  - Added Oleg Semyonov's changes for IAR-cc compatibility.
-  - Added new (optional) functions usbDeviceConnect() and usbDeviceDisconnect()
-    (also thanks to Oleg!).
-  - Rearranged tests in usbPoll() to save a couple of instructions in the most
-    likely case that no actions are pending.
-  - We need a delay between the SET ADDRESS request until the new address
-    becomes active. This delay was handled in usbPoll() until now. Since the
-    spec says that the delay must not exceed 2ms, previous versions required
-    aggressive polling during the enumeration phase. We have now moved the
-    handling of the delay into the interrupt routine.
-  - We must not reply with NAK to a SETUP transaction. We can only achieve this
-    by making sure that the rx buffer is empty when SETUP tokens are expected.
-    We therefore don't pass zero sized data packets from the status phase of
-    a transfer to usbPoll(). This change MAY cause troubles if you rely on
-    receiving a less than 8 bytes long packet in usbFunctionWrite() to
-    identify the end of a transfer. usbFunctionWrite() will NEVER be called
-    with a zero length.
-
-* Release 2006-03-14
-
-  - Improved IAR C support: tiny memory model, more devices
-  - Added template usbconfig.h file under the name usbconfig-prototype.h
-
-* Release 2006-03-26
-
-  - Added provision for one more interrupt-in endpoint (endpoint 3).
-  - Added provision for one interrupt-out endpoint (endpoint 1).
-  - Added flowcontrol macros for USB.
-  - Added provision for custom configuration descriptor.
-  - Allow ANY two port bits for D+ and D-.
-  - Merged (optional) receive endpoint number into global usbRxToken variable.
-  - Use USB_CFG_IOPORTNAME instead of USB_CFG_IOPORT. We now construct the
-    variable name from the single port letter instead of computing the address
-    of related ports from the output-port address.
-
-* Release 2006-06-26
-
-  - Updated documentation in usbdrv.h and usbconfig-prototype.h to reflect the
-    new features.
-  - Removed "#warning" directives because IAR does not understand them. Use
-    unused static variables instead to generate a warning.
-  - Do not include <avr/io.h> when compiling with IAR.
-  - Introduced USB_CFG_DESCR_PROPS_* in usbconfig.h to configure how each
-    USB descriptor should be handled. It is now possible to provide descriptor
-    data in Flash, RAM or dynamically at runtime.
-  - STALL is now a status in usbTxLen* instead of a message. We can now conform
-    to the spec and leave the stall status pending until it is cleared.
-  - Made usbTxPacketCnt1 and usbTxPacketCnt3 public. This allows the
-    application code to reset data toggling on interrupt pipes.
-
-* Release 2006-07-18
-
-  - Added an #if !defined __ASSEMBLER__ to the warning in usbdrv.h. This fixes
-    an assembler error.
-  - usbDeviceDisconnect() takes pull-up resistor to high impedance now.
-
-* Release 2007-02-01
-
-  - Merged in some code size improvements from usbtiny (thanks to Dick
-    Streefland for these optimizations!)
-  - Special alignment requirement for usbRxBuf not required any more. Thanks
-    again to Dick Streefland for this hint!
-  - Reverted to "#warning" instead of unused static variables -- new versions
-    of IAR CC should handle this directive.
-  - Changed Open Source license to GNU GPL v2 in order to make linking against
-    other free libraries easier. We no longer require publication of the
-    circuit diagrams, but we STRONGLY encourage it. If you improve the driver
-    itself, PLEASE grant us a royalty free license to your changes for our
-    commercial license.
-
-* Release 2007-03-29
-
-  - New configuration option "USB_PUBLIC" in usbconfig.h.
-  - Set USB version number to 1.10 instead of 1.01.
-  - Code used USB_CFG_DESCR_PROPS_STRING_DEVICE and
-    USB_CFG_DESCR_PROPS_STRING_PRODUCT inconsistently. Changed all occurrences
-    to USB_CFG_DESCR_PROPS_STRING_PRODUCT.
-  - New assembler module for 16.5 MHz RC oscillator clock with PLL in receiver
-    code.
-  - New assembler module for 16 MHz crystal.
-  - usbdrvasm.S contains common code only, clock-specific parts have been moved
-    to usbdrvasm12.S, usbdrvasm16.S and usbdrvasm165.S respectively.
-
-* Release 2007-06-25
-
-  - 16 MHz module: Do SE0 check in stuffed bits as well.
-
-* Release 2007-07-07
-
-  - Define hi8(x) for IAR compiler to limit result to 8 bits. This is necessary
-    for negative values.
-  - Added 15 MHz module contributed by V. Bosch.
-  - Interrupt vector name can now be configured. This is useful if somebody
-    wants to use a different hardware interrupt than INT0.
-
-* Release 2007-08-07
-
-  - Moved handleIn3 routine in usbdrvasm16.S so that relative jump range is
-    not exceeded.
-  - More config options: USB_RX_USER_HOOK(), USB_INITIAL_DATATOKEN,
-    USB_COUNT_SOF
-  - USB_INTR_PENDING can now be a memory address, not just I/O
-
-* Release 2007-09-19
-
-  - Split out common parts of assembler modules into separate include file
-  - Made endpoint numbers configurable so that given interface definitions
-    can be matched. See USB_CFG_EP3_NUMBER in usbconfig-prototype.h.
-  - Store endpoint number for interrupt/bulk-out so that usbFunctionWriteOut()
-    can handle any number of endpoints.
-  - Define usbDeviceConnect() and usbDeviceDisconnect() even if no
-    USB_CFG_PULLUP_IOPORTNAME is defined. Directly set D+ and D- to 0 in this
-    case.
-
-* Release 2007-12-01
-
-  - Optimize usbDeviceConnect() and usbDeviceDisconnect() for less code size
-    when USB_CFG_PULLUP_IOPORTNAME is not defined.
-
-* Release 2007-12-13
-
-  - Renamed all include-only assembler modules from *.S to *.inc so that
-    people don't add them to their project sources.
-  - Distribute leap bits in tx loop more evenly for 16 MHz module.
-  - Use "macro" and "endm" instead of ".macro" and ".endm" for IAR
-  - Avoid compiler warnings for constant expr range by casting some values in
-    USB descriptors.
-
-* Release 2008-01-21
-
-  - Fixed bug in 15 and 16 MHz module where the new address set with
-    SET_ADDRESS was already accepted at the next NAK or ACK we send, not at
-    the next data packet we send. This caused problems when the host polled
-    too fast. Thanks to Alexander Neumann for his help and patience debugging
-    this issue!
-
-* Release 2008-02-05
-
-  - Fixed bug in 16.5 MHz module where a register was used in the interrupt
-    handler before it was pushed. This bug was introduced with version
-    2007-09-19 when common parts were moved to a separate file.
-  - Optimized CRC routine (thanks to Reimar Doeffinger).
-
-* Release 2008-02-16
-
-  - Removed outdated IAR compatibility stuff (code sections).
-  - Added hook macros for USB_RESET_HOOK() and USB_SET_ADDRESS_HOOK().
-  - Added optional routine usbMeasureFrameLength() for calibration of the
-    internal RC oscillator.
-
-* Release 2008-02-28
-
-  - USB_INITIAL_DATATOKEN defaults to USBPID_DATA1 now, which means that we
-    start with sending USBPID_DATA0.
-  - Changed defaults in usbconfig-prototype.h
-  - Added free USB VID/PID pair for MIDI class devices
-  - Restructured AVR-USB as separate package, not part of PowerSwitch any more.
-
-* Release 2008-04-18
-
-  - Restructured usbdrv.c so that it is easier to read and understand.
-  - Better code optimization with gcc 4.
-  - If a second interrupt in endpoint is enabled, also add it to config
-    descriptor.
-  - Added config option for long transfers (above 254 bytes), see
-    USB_CFG_LONG_TRANSFERS in usbconfig.h.
-  - Added 20 MHz module contributed by Jeroen Benschop.
-
-* Release 2008-05-13
-
-  - Fixed bug in libs-host/hiddata.c function usbhidGetReport(): length
-    was not incremented, pointer to length was incremented instead.
-  - Added code to command line tool(s) which claims an interface. This code
-    is disabled by default, but may be necessary on newer Linux kernels.
-  - Added usbconfig.h option "USB_CFG_CHECK_DATA_TOGGLING".
-  - New header "usbportability.h" prepares ports to other development
-    environments.
-  - Long transfers (above 254 bytes) did not work when usbFunctionRead() was
-    used to supply the data. Fixed this bug. [Thanks to Alexander Neumann!]
-  - In hiddata.c (example code for sending/receiving data over HID), use
-    USB_RECIP_DEVICE instead of USB_RECIP_INTERFACE for control transfers so
-    that we need not claim the interface.
-  - in usbPoll() loop 20 times polling for RESET state instead of 10 times.
-    This accounts for the higher clock rates we now support.
-  - Added a module for 12.8 MHz RC oscillator with PLL in receiver loop.
-  - Added hook to SOF code so that oscillator can be tuned to USB frame clock.
-  - Added timeout to waitForJ loop. Helps preventing unexpected hangs.
-  - Added example code for oscillator tuning to libs-device (thanks to
-    Henrik Haftmann for the idea to this routine).
-  - Implemented option USB_CFG_SUPPRESS_INTR_CODE.
-
-* Release 2008-10-22
-
-  - Fixed libs-device/osctune.h: OSCCAL is memory address on ATMega88 and
-    similar, not offset of 0x20 needs to be added.
-  - Allow distribution under GPLv3 for those who have to link against other
-    code distributed under GPLv3.
-
-* Release 2008-11-26
-
-  - Removed libusb-win32 dependency for hid-data example in Makefile.windows.
-    It was never required and confused many people.
-  - Added extern uchar usbRxToken to usbdrv.h.
-  - Integrated a module with CRC checks at 18 MHz by Lukas Schrittwieser.
-
-* Release 2009-03-23
-
-  - Hid-mouse example used settings from hid-data example, fixed that.
-  - Renamed project to V-USB due to a trademark issue with Atmel(r).
-  - Changed CommercialLicense.txt and USBID-License.txt to make the
-    background of USB ID registration clearer.
-
-* Release 2009-04-15
-
-  - Changed CommercialLicense.txt to reflect the new range of PIDs from
-    Jason Kotzin.
-  - Removed USBID-License.txt in favor of USB-IDs-for-free.txt and
-    USB-ID-FAQ.txt
-  - Fixed a bug in the 12.8 MHz module: End Of Packet decection was made in
-    the center between bit 0 and 1 of each byte. This is where the data lines
-    are expected to change and the sampled data may therefore be nonsense.
-    We therefore check EOP ONLY if bits 0 AND 1 have both been read as 0 on D-.
-  - Fixed a bitstuffing problem in the 16 MHz module: If bit 6 was stuffed,
-    the unstuffing code in the receiver routine was 1 cycle too long. If
-    multiple bytes had the unstuffing in bit 6, the error summed up until the
-    receiver was out of sync.
-  - Included option for faster CRC routine.
-    Thanks to Slawomir Fras (BoskiDialer) for this code!
-  - Updated bits in Configuration Descriptor's bmAttributes according to
-    USB 1.1 (in particular bit 7, it is a must-be-set bit now).
-
-* Release 2009-08-22
-
-  - Moved first DBG1() after odDebugInit() in all examples.
-  - Use vector INT0_vect instead of SIG_INTERRUPT0 if defined. This makes
-    V-USB compatible with the new "p" suffix devices (e.g. ATMega328p).
-  - USB_CFG_CLOCK_KHZ setting is now required in usbconfig.h (no default any
-    more).
-  - New option USB_CFG_DRIVER_FLASH_PAGE allows boot loaders on devices with
-    more than 64 kB flash.
-  - Built-in configuration descriptor allows custom definition for second
-    endpoint now.
-
-* Release 2010-07-15
-
-  - Fixed bug in usbDriverSetup() which prevented descriptor sizes above 255
-    bytes.
-  - Avoid a compiler warning for unused parameter in usbHandleResetHook() when
-    compiler option -Wextra is enabled.
-  - Fixed wrong hex value for some IDs in USB-IDs-for-free.txt.
-  - Keep a define for USBATTR_BUSPOWER, although the flag does not exist
-    in USB 1.1 any more. Set it to 0. This is for backward compatibility.
-
-* Release 2012-01-09
-
-  - Define a separate (defined) type for usbMsgPtr so that projects using a
-    tiny memory model can define it to an 8 bit type in usbconfig.h. This
-    change also saves a couple of bytes when using a scalar 16 bit type.
-  - Inserted "const" keyword for all PROGMEM declarations because new GCC
-    requires it.
-  - Fixed problem with dependence of usbportability.h on usbconfig.h. This
-    problem occurred with IAR CC only.
-  - Prepared repository for github.com.
-
-* Release 2012-12-06

-V-USB Driver Software License Agreement
-Version 2012-07-09
-
-THIS LICENSE AGREEMENT GRANTS YOU CERTAIN RIGHTS IN A SOFTWARE. YOU CAN
-ENTER INTO THIS AGREEMENT AND ACQUIRE THE RIGHTS OUTLINED BELOW BY PAYING
-THE AMOUNT ACCORDING TO SECTION 4 ("PAYMENT") TO OBJECTIVE DEVELOPMENT.
-
-
-1 DEFINITIONS
-
-1.1 "OBJECTIVE DEVELOPMENT" shall mean OBJECTIVE DEVELOPMENT Software GmbH,
-Grosse Schiffgasse 1A/7, 1020 Wien, AUSTRIA.
-
-1.2 "You" shall mean the Licensee.
-
-1.3 "V-USB" shall mean all files included in the package distributed under
-the name "vusb" by OBJECTIVE DEVELOPMENT (http://www.obdev.at/vusb/)
-unless otherwise noted. This includes the firmware-only USB device
-implementation for Atmel AVR microcontrollers, some simple device examples
-and host side software examples and libraries.
-
-
-2 LICENSE GRANTS
-
-2.1 Source Code. OBJECTIVE DEVELOPMENT shall furnish you with the source
-code of V-USB.
-
-2.2 Distribution and Use. OBJECTIVE DEVELOPMENT grants you the
-non-exclusive right to use, copy and distribute V-USB with your hardware
-product(s), restricted by the limitations in section 3 below.
-
-2.3 Modifications. OBJECTIVE DEVELOPMENT grants you the right to modify
-the source code and your copy of V-USB according to your needs.
-
-2.4 USB IDs. OBJECTIVE DEVELOPMENT furnishes you with one or two USB
-Product ID(s), sent to you in e-mail. These Product IDs are reserved
-exclusively for you. OBJECTIVE DEVELOPMENT has obtained USB Product ID
-ranges under the Vendor ID 5824 from Wouter van Ooijen (Van Ooijen
-Technische Informatica, www.voti.nl) and under the Vendor ID 8352 from
-Jason Kotzin (now flirc.tv, Inc.). Both owners of the Vendor IDs have
-obtained these IDs from the USB Implementers Forum, Inc. (www.usb.org).
-OBJECTIVE DEVELOPMENT disclaims all liability which might arise from the
-assignment of USB IDs.
-
-2.5 USB Certification. Although not part of this agreement, we want to make
-it clear that you cannot become USB certified when you use V-USB or a USB
-Product ID assigned by OBJECTIVE DEVELOPMENT. AVR microcontrollers don't
-meet the electrical specifications required by the USB specification and
-the USB Implementers Forum certifies only members who bought a Vendor ID of
-their own.
-
-
-3 LICENSE RESTRICTIONS
-
-3.1 Number of Units. Only one of the following three definitions is
-applicable. Which one is determined by the amount you pay to OBJECTIVE
-DEVELOPMENT, see section 4 ("Payment") below.
-
-Hobby License: You may use V-USB according to section 2 above in no more
-than 5 hardware units. These units must not be sold for profit.
-
-Entry Level License: You may use V-USB according to section 2 above in no
-more than 150 hardware units.
-
-Professional License: You may use V-USB according to section 2 above in
-any number of hardware units, except for large scale production ("unlimited
-fair use"). Quantities below 10,000 units are not considered large scale
-production. If your reach quantities which are obviously large scale
-production, you must pay a license fee of 0.10 EUR per unit for all units
-above 10,000.
-
-3.2 Rental. You may not rent, lease, or lend V-USB or otherwise encumber
-any copy of V-USB, or any of the rights granted herein.
-
-3.3 Transfer. You may not transfer your rights under this Agreement to
-another party without OBJECTIVE DEVELOPMENT's prior written consent. If
-such consent is obtained, you may permanently transfer this License to
-another party. The recipient of such transfer must agree to all terms and
-conditions of this Agreement.
-
-3.4 Reservation of Rights. OBJECTIVE DEVELOPMENT retains all rights not
-expressly granted.
-
-3.5 Non-Exclusive Rights. Your license rights under this Agreement are
-non-exclusive.
-
-3.6 Third Party Rights. This Agreement cannot grant you rights controlled
-by third parties. In particular, you are not allowed to use the USB logo or
-other trademarks owned by the USB Implementers Forum, Inc. without their
-consent. Since such consent depends on USB certification, it should be
-noted that V-USB will not pass certification because it does not
-implement checksum verification and the microcontroller ports do not meet
-the electrical specifications.
-
-
-4 PAYMENT
-
-The payment amount depends on the variation of this agreement (according to
-section 3.1) into which you want to enter. Concrete prices are listed on
-OBJECTIVE DEVELOPMENT's web site, usually at
-http://www.obdev.at/vusb/license.html. You agree to pay the amount listed
-there to OBJECTIVE DEVELOPMENT or OBJECTIVE DEVELOPMENT's payment processor
-or reseller.
-
-
-5 COPYRIGHT AND OWNERSHIP
-
-V-USB is protected by copyright laws and international copyright
-treaties, as well as other intellectual property laws and treaties. V-USB
-is licensed, not sold.
-
-
-6 TERM AND TERMINATION
-
-6.1 Term. This Agreement shall continue indefinitely. However, OBJECTIVE
-DEVELOPMENT may terminate this Agreement and revoke the granted license and
-USB-IDs if you fail to comply with any of its terms and conditions.
-
-6.2 Survival of Terms. All provisions regarding secrecy, confidentiality
-and limitation of liability shall survive termination of this agreement.
-
-

- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-                            NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-CPU CORE CLOCK FREQUENCY
-========================
-We supply assembler modules for clock frequencies of 12 MHz, 12.8 MHz, 15 MHz,
-16 MHz, 16.5 MHz 18 MHz and 20 MHz. Other clock rates are not supported. The
-actual clock rate must be configured in usbconfig.h.
-
-12 MHz Clock
-This is the traditional clock rate of V-USB because it's the lowest clock
-rate where the timing constraints of the USB spec can be met.
-
-15 MHz Clock
-Similar to 12 MHz, but some NOPs inserted. On the other hand, the higher clock
-rate allows for some loops which make the resulting code size somewhat smaller
-than the 12 MHz version.
-
-16 MHz Clock
-This clock rate has been added for users of the Arduino board and other
-ready-made boards which come with a fixed 16 MHz crystal. It's also an option
-if you need the slightly higher clock rate for performance reasons. Since
-16 MHz is not divisible by the USB low speed bit clock of 1.5 MHz, the code
-is somewhat tricky and has to insert a leap cycle every third byte.
-
-12.8 MHz and 16.5 MHz Clock
-The assembler modules for these clock rates differ from the other modules
-because they have been built for an RC oscillator with only 1% precision. The
-receiver code inserts leap cycles to compensate for clock deviations. 1% is
-also the precision which can be achieved by calibrating the internal RC
-oscillator of the AVR. Please note that only AVRs with internal 64 MHz PLL
-oscillator can reach 16.5 MHz with the RC oscillator. This includes the very
-popular ATTiny25, ATTiny45, ATTiny85 series as well as the ATTiny26. Almost
-all AVRs can reach 12.8 MHz, although this is outside the specified range.
-
-See the EasyLogger example at http://www.obdev.at/vusb/easylogger.html for
-code which calibrates the RC oscillator based on the USB frame clock.
-
-18 MHz Clock
-This module is closer to the USB specification because it performs an on the
-fly CRC check for incoming packets. Packets with invalid checksum are
-discarded as required by the spec. If you also implement checks for data
-PID toggling on application level (see option USB_CFG_CHECK_DATA_TOGGLING
-in usbconfig.h for more info), this ensures data integrity. Due to the CRC
-tables and alignment requirements, this code is bigger than modules for other
-clock rates. To activate this module, you must define USB_CFG_CHECK_CRC to 1
-and USB_CFG_CLOCK_KHZ to 18000 in usbconfig.h.
-
-20 MHz Clock
-This module is for people who won't do it with less than the maximum. Since
-20 MHz is not divisible by the USB low speed bit clock of 1.5 MHz, the code
-uses similar tricks as the 16 MHz module to insert leap cycles.
-
-
-USB IDENTIFIERS
-===============
-Every USB device needs a vendor- and a product-identifier (VID and PID). VIDs
-are obtained from usb.org for a price of 1,500 USD. Once you have a VID, you
-can assign PIDs at will.
-
-Since an entry level cost of 1,500 USD is too high for most small companies
-and hobbyists, we provide some VID/PID pairs for free. See the file
-USB-IDs-for-free.txt for details.
-
-Objective Development also has some license offerings which include product
-IDs. See http://www.obdev.at/vusb/ for details.
-
-
-DEVELOPMENT SYSTEM
-==================
-This driver has been developed and optimized for the GNU compiler version 3
-and 4. We recommend that you use the GNU compiler suite because it is freely
-available. V-USB has also been ported to the IAR compiler and assembler. It
-has been tested with IAR 4.10B/W32 and 4.12A/W32 on an ATmega8 with the
-"small" and "tiny" memory model. Not every release is tested with IAR CC and
-the driver may therefore fail to compile with IAR. Please note that gcc is
-more efficient for usbdrv.c because this module has been deliberately
-optimized for gcc.
-
-Gcc version 3 produces smaller code than version 4 due to new optimizing
-capabilities which don't always improve things on 8 bit CPUs. The code size
-generated by gcc 4 can be reduced with the compiler options
--fno-move-loop-invariants, -fno-tree-scev-cprop and
--fno-inline-small-functions in addition to -Os. On devices with more than
-8k of flash memory, we also recommend the linker option --relax (written as
--Wl,--relax for gcc) to convert absolute calls into relative where possible.
-
-For more information about optimizing options see:
-
-    http://www.tty1.net/blog/2008-04-29-avr-gcc-optimisations_en.html
-
-These optimizations are good for gcc 4.x. Version 3.x of gcc does not support
-most of these options and produces good code anyway.
-
-
-USING V-USB FOR FREE
-====================
-The AVR firmware driver is published under the GNU General Public License
-Version 2 (GPL2) and the GNU General Public License Version 3 (GPL3). It is
-your choice whether you apply the terms of version 2 or version 3.
-
-If you decide for the free GPL2 or GPL3, we STRONGLY ENCOURAGE you to do the
-following things IN ADDITION to the obligations from the GPL:
-
-(1) Publish your entire project on a web site and drop us a note with the URL.
-Use the form at http://www.obdev.at/vusb/feedback.html for your submission.
-If you don't have a web site, you can publish the project in obdev's
-documentation wiki at
-http://www.obdev.at/goto.php?t=vusb-wiki&p=hosted-projects.
-
-(2) Adhere to minimum publication standards. Please include AT LEAST:
-    - a circuit diagram in PDF, PNG or GIF format
-    - full source code for the host software
-    - a Readme.txt file in ASCII format which describes the purpose of the
-      project and what can be found in which directories and which files
-    - a reference to http://www.obdev.at/vusb/
-
-(3) If you improve the driver firmware itself, please give us a free license
-to your modifications for our commercial license offerings.
-
-
-COMMERCIAL LICENSES FOR V-USB
-=============================
-If you don't want to publish your source code under the terms of the GPL,
-you can simply pay money for V-USB. As an additional benefit you get
-USB PIDs for free, reserved exclusively to you. See the file
-"CommercialLicense.txt" for details.

-Version 2012-07-09
-
-==========================
-WHY DO WE NEED THESE IDs?
-==========================
-
-USB is more than a low level protocol for data transport. It also defines a
-common set of requests which must be understood by all devices. And as part
-of these common requests, the specification defines data structures, the
-USB Descriptors, which are used to describe the properties of the device.
-
-From the perspective of an operating system, it is therefore possible to find
-out basic properties of a device (such as e.g. the manufacturer and the name
-of the device) without a device-specific driver. This is essential because
-the operating system can choose a driver to load based on this information
-(Plug-And-Play).
-
-Among the most important properties in the Device Descriptor are the USB
-Vendor- and Product-ID. Both are 16 bit integers. The most simple form of
-driver matching is based on these IDs. The driver announces the Vendor- and
-Product-IDs of the devices it can handle and the operating system loads the
-appropriate driver when the device is connected.
-
-It is obvious that this technique only works if the pair Vendor- plus
-Product-ID is unique: Only devices which require the same driver can have the
-same pair of IDs.
-
-
-=====================================================
-HOW DOES THE USB STANDARD ENSURE THAT IDs ARE UNIQUE?
-=====================================================
-
-Since it is so important that USB IDs are unique, the USB Implementers Forum,
-Inc. (usb.org) needs a way to enforce this legally. It is not forbidden by
-law to build a device and assign it any random numbers as IDs. Usb.org
-therefore needs an agreement to regulate the use of USB IDs. The agreement
-binds only parties who agreed to it, of course. Everybody else is free to use
-any numbers for their IDs.
-
-So how can usb.org ensure that every manufacturer of USB devices enters into
-an agreement with them? They do it via trademark licensing. Usb.org has
-registered the trademark "USB", all associated logos and related terms. If
-you want to put an USB logo on your product or claim that it is USB
-compliant, you must license these trademarks from usb.org. And this is where
-you enter into an agreement. See the "USB-IF Trademark License Agreement and
-Usage Guidelines for the USB-IF Logo" at
-http://www.usb.org/developers/logo_license/.
-
-Licensing the USB trademarks requires that you buy a USB Vendor-ID from
-usb.org (one-time fee of ca. 2,000 USD), that you become a member of usb.org
-(yearly fee of ca. 4,000 USD) and that you meet all the technical
-specifications from the USB spec.
-
-This means that most hobbyists and small companies will never be able to
-become USB compliant, just because membership is so expensive. And you can't
-be compliant with a driver based on V-USB anyway, because the AVR's port pins
-don't meet the electrical specifications for USB. So, in principle, all
-hobbyists and small companies are free to choose any random numbers for their
-IDs. They have nothing to lose...
-
-There is one exception worth noting, though: If you use a sub-component which
-implements USB, the vendor of the sub-components may guarantee USB
-compliance. This might apply to some or all of FTDI's solutions.
-
-
-=======================================================================
-WHY SHOULD YOU OBTAIN USB IDs EVEN IF YOU DON'T LICENSE USB TRADEMARKS?
-=======================================================================
-
-You have learned in the previous section that you are free to choose any
-numbers for your IDs anyway. So why not do exactly this? There is still the
-technical issue. If you choose IDs which are already in use by somebody else,
-operating systems will load the wrong drivers and your device won't work.
-Even if you choose IDs which are not currently in use, they may be in use in
-the next version of the operating system or even after an automatic update.
-
-So what you need is a pair of Vendor- and Product-IDs for which you have the
-guarantee that no USB compliant product uses them. This implies that no
-operating system will ever ship with drivers responsible for these IDs.
-
-
-==============================================
-HOW DOES OBJECTIVE DEVELOPMENT HANDLE USB IDs?
-==============================================
-
-Objective Development gives away pairs of USB-IDs with their V-USB licenses.
-In order to ensure that these IDs are unique, Objective Development has an
-agreement with the company/person who has bought the USB Vendor-ID from
-usb.org. This agreement ensures that a range of USB Product-IDs is reserved
-for assignment by Objective Development and that the owner of the Vendor-ID
-won't give it to anybody else.
-
-This means that you have to trust three parties to ensure uniqueness of
-your IDs:
-
-  - Objective Development, that they don't give the same PID to more than
-    one person.
-  - The owner of the Vendor-ID that they don't assign PIDs from the range
-    assigned to Objective Development to anybody else.
-  - Usb.org that they don't assign the same Vendor-ID a second time.
-
-
-==================================
-WHO IS THE OWNER OF THE VENDOR-ID?
-==================================
-
-Objective Development has obtained ranges of USB Product-IDs under two
-Vendor-IDs: Under Vendor-ID 5824 from Wouter van Ooijen (Van Ooijen
-Technische Informatica, www.voti.nl) and under Vendor-ID 8352 from Jason
-Kotzin (now flirc.tv, Inc.). Both VID owners have received their Vendor-ID
-directly from usb.org.
-
-
-=========================================================================
-CAN I USE USB-IDs FROM OBJECTIVE DEVELOPMENT WITH OTHER DRIVERS/HARDWARE?
-=========================================================================
-
-The short answer is: Yes. All you get is a guarantee that the IDs are never
-assigned to anybody else. What more do you need?
-
-
-============================
-WHAT ABOUT SHARED ID PAIRS?
-============================
-
-Objective Development has reserved some PID/VID pairs for shared use. You
-have no guarantee of uniqueness for them, except that no USB compliant device
-uses them. In order to avoid technical problems, we must ensure that all
-devices with the same pair of IDs use the same driver on kernel level. For
-details, see the file USB-IDs-for-free.txt.
-
-
-======================================================
-I HAVE HEARD THAT SUB-LICENSING OF USB-IDs IS ILLEGAL?
-======================================================
-
-A 16 bit integer number cannot be protected by copyright laws. It is not
-sufficiently complex. And since none of the parties involved entered into the
-USB-IF Trademark License Agreement, we are not bound by this agreement. So
-there is no reason why it should be illegal to sub-license USB-IDs.
-
-
-=============================================
-WHO IS LIABLE IF THERE ARE INCOMPATIBILITIES?
-=============================================
-
-Objective Development disclaims all liabilities which might arise from the
-assignment of IDs. If you guarantee product features to your customers
-without proper disclaimer, YOU are liable for that.

-
-===========================
-FREE USB-IDs FOR SHARED USE
-===========================
-
-Objective Development has reserved a set of USB Product-IDs for use according
-to the guidelines outlined below. For more information about the concept of
-USB IDs please see the file USB-ID-FAQ.txt. Objective Development guarantees
-that the IDs listed below are not used by any USB compliant devices.
-
-
-====================
-MECHANISM OF SHARING
-====================
-
-From a technical point of view, two different devices can share the same USB
-Vendor- and Product-ID if they require the same driver on operating system
-level. We make use of this fact by assigning separate IDs for various device
-classes. On application layer, devices must be distinguished by their textual
-name or serial number. We offer separate sets of IDs for discrimination by
-textual name and for serial number.
-
-Examples for shared use of USB IDs are included with V-USB in the "examples"
-subdirectory.
-
-
-======================================
-IDs FOR DISCRIMINATION BY TEXTUAL NAME
-======================================
-
-If you use one of the IDs listed below, your device and host-side software
-must conform to these rules:
-
-(1) The USB device MUST provide a textual representation of the manufacturer
-and product identification. The manufacturer identification MUST be available
-at least in USB language 0x0409 (English/US).
-
-(2) The textual manufacturer identification MUST contain either an Internet
-domain name (e.g. "mycompany.com") registered and owned by you, or an e-mail
-address under your control (e.g. "myname@gmx.net"). You can embed the domain
-name or e-mail address in any string you like, e.g.  "Objective Development
-http://www.obdev.at/vusb/".
-
-(3) You are responsible for retaining ownership of the domain or e-mail
-address for as long as any of your products are in use.
-
-(4) You may choose any string for the textual product identification, as long
-as this string is unique within the scope of your textual manufacturer
-identification.
-
-(5) Application side device look-up MUST be based on the textual manufacturer
-and product identification in addition to VID/PID matching. The driver
-matching MUST be a comparison of the entire strings, NOT a sub-string match.
-
-(6) For devices which implement a particular USB device class (e.g. HID), the
-operating system's default class driver MUST be used. If an operating system
-driver for Vendor Class devices is needed, this driver must be libusb or
-libusb-win32 (see http://libusb.org/ and
-http://libusb-win32.sourceforge.net/).
-
-Table if IDs for discrimination by textual name:
-
-PID dec (hex) | VID dec (hex) | Description of use
-==============+===============+============================================
-1500 (0x05dc) | 5824 (0x16c0) | For Vendor Class devices with libusb
---------------+---------------+--------------------------------------------
-1503 (0x05df) | 5824 (0x16c0) | For generic HID class devices (which are
-              |               | NOT mice, keyboards or joysticks)
---------------+---------------+--------------------------------------------
-1505 (0x05e1) | 5824 (0x16c0) | For CDC-ACM class devices (modems)
---------------+---------------+--------------------------------------------
-1508 (0x05e4) | 5824 (0x16c0) | For MIDI class devices
---------------+---------------+--------------------------------------------
-
-Note that Windows caches the textual product- and vendor-description for
-mice, keyboards and joysticks. Name-bsed discrimination is therefore not
-recommended for these device classes.
-
-
-=======================================
-IDs FOR DISCRIMINATION BY SERIAL NUMBER
-=======================================
-
-If you use one of the IDs listed below, your device and host-side software
-must conform to these rules:
-
-(1) The USB device MUST provide a textual representation of the serial
-number, unless ONLY the operating system's default class driver is used.
-The serial number string MUST be available at least in USB language 0x0409
-(English/US).
-
-(2) The serial number MUST start with either an Internet domain name (e.g.
-"mycompany.com") registered and owned by you, or an e-mail address under your
-control (e.g. "myname@gmx.net"), both terminated with a colon (":") character.
-You MAY append any string you like for further discrimination of your devices.
-
-(3) You are responsible for retaining ownership of the domain or e-mail
-address for as long as any of your products are in use.
-
-(5) Application side device look-up MUST be based on the serial number string
-in addition to VID/PID matching. The matching must start at the first
-character of the serial number string and include the colon character
-terminating your domain or e-mail address. It MAY stop anywhere after that.
-
-(6) For devices which implement a particular USB device class (e.g. HID), the
-operating system's default class driver MUST be used. If an operating system
-driver for Vendor Class devices is needed, this driver must be libusb or
-libusb-win32 (see http://libusb.org/ and
-http://libusb-win32.sourceforge.net/).
-
-(7) If ONLY the operating system's default class driver is used, e.g. for
-mice, keyboards, joysticks, CDC or MIDI devices and no discrimination by an
-application is needed, the serial number may be omitted.
-
-
-Table if IDs for discrimination by serial number string:
-
-PID dec (hex)  | VID dec (hex) | Description of use
-===============+===============+===========================================
-10200 (0x27d8) | 5824 (0x16c0) | For Vendor Class devices with libusb
----------------+---------------+-------------------------------------------
-10201 (0x27d9) | 5824 (0x16c0) | For generic HID class devices (which are
-               |               | NOT mice, keyboards or joysticks)

- * no properties are defined or if they are 0, the default descriptor is used.
- * Possible properties are:
- *   + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
- *     at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
- *     used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if

- *   + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
- *     in static memory is in RAM, not in flash memory.
- *   + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
- *     the driver must know the descriptor's length. The descriptor itself is
- *     found at the address of a well known identifier (see below).
- * List of static descriptor names (must be declared PROGMEM if in flash):
- *   char usbDescriptorDevice[];
- *   char usbDescriptorConfiguration[];
- *   char usbDescriptorHidReport[];
- *   char usbDescriptorString0[];
- *   int usbDescriptorStringVendor[];
- *   int usbDescriptorStringDevice[];
- *   int usbDescriptorStringSerialNumber[];
- * Other descriptors can't be provided statically, they must be provided
- * dynamically at runtime.
- *
- * Descriptor properties are or-ed or added together, e.g.:
- * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
- *
- * The following descriptors are defined:

- *   USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
- *

- * are Unicode strings prefixed with a 2 byte header. Example:

- * information about this function.

- * no properties are defined or if they are 0, the default descriptor is used.
- * Possible properties are:
- *   + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
- *     at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
- *     used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if

- *     in static memory is in RAM, not in flash memory.
- *   + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
- *     the driver must know the descriptor's length. The descriptor itself is
- *     found at the address of a well known identifier (see below).
- * List of static descriptor names (must be declared PROGMEM if in flash):
- *   char usbDescriptorDevice[];
- *   char usbDescriptorConfiguration[];
- *   char usbDescriptorHidReport[];
- *   char usbDescriptorString0[];
- *   int usbDescriptorStringVendor[];
- *   int usbDescriptorStringDevice[];
- *   int usbDescriptorStringSerialNumber[];
- * Other descriptors can't be provided statically, they must be provided
- * dynamically at runtime.
- *
- * Descriptor properties are or-ed or added together, e.g.:
- * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
- *
- * The following descriptors are defined:
- *   USB_CFG_DESCR_PROPS_DEVICE
- *   USB_CFG_DESCR_PROPS_CONFIGURATION
- *   USB_CFG_DESCR_PROPS_STRINGS

- *   USB_CFG_DESCR_PROPS_HID_REPORT
- *   USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
- *

- * are Unicode strings prefixed with a 2 byte header. Example:
- * int  serialNumberDescriptor[] = {
- *     USB_STRING_DESCRIPTOR_HEADER(6),
- *     'S', 'e', 'r', 'i', 'a', 'l'

-Hardware Prerequisites:
-=======================
-USB lines D+ and D- MUST be wired to the same I/O port. We recommend that D+
-triggers the interrupt (best achieved by using INT0 for D+), but it is also
-possible to trigger the interrupt from D-. If D- is used, interrupts are also
-triggered by SOF packets. D- requires a pull-up of 1.5k to +3.5V (and the
-device must be powered at 3.5V) to identify as low-speed USB device. A
-pull-down or pull-up of 1M SHOULD be connected from D+ to +3.5V to prevent
-interference when no USB master is connected. If you use Zener diodes to limit
-the voltage on D+ and D-, you MUST use a pull-down resistor, not a pull-up.
-We use D+ as interrupt source and not D- because it does not trigger on
-keep-alive and RESET states. If you want to count keep-alive events with
-USB_COUNT_SOF, you MUST use D- as an interrupt source.
-
-As a compile time option, the 1.5k pull-up resistor on D- can be made
-switchable to allow the device to disconnect at will. See the definition of
-usbDeviceConnect() and usbDeviceDisconnect() further down in this file.
-
-Please adapt the values in usbconfig.h according to your hardware!
-
-The device MUST be clocked at exactly 12 MHz, 15 MHz, 16 MHz or 20 MHz
-or at 12.8 MHz resp. 16.5 MHz +/- 1%. See usbconfig-prototype.h for details.
-
-
-Limitations:
-============
-Robustness with respect to communication errors:
-The driver assumes error-free communication. It DOES check for errors in
-the PID, but does NOT check bit stuffing errors, SE0 in middle of a byte,
-token CRC (5 bit) and data CRC (16 bit). CRC checks can not be performed due
-to timing constraints: We must start sending a reply within 7 bit times.
-Bit stuffing and misplaced SE0 would have to be checked in real-time, but CPU
-performance does not permit that. The driver does not check Data0/Data1
-toggling, but application software can implement the check.
-
-Input characteristics:
-Since no differential receiver circuit is used, electrical interference
-robustness may suffer. The driver samples only one of the data lines with
-an ordinary I/O pin's input characteristics. However, since this is only a
-low speed USB implementation and the specification allows for 8 times the
-bit rate over the same hardware, we should be on the safe side. Even the spec
-requires detection of asymmetric states at high bit rate for SE0 detection.
-
-Number of endpoints:
-The driver supports the following endpoints:
-
-- Endpoint 0, the default control endpoint.
-- Any number of interrupt- or bulk-out endpoints. The data is sent to
-  usbFunctionWriteOut() and USB_CFG_IMPLEMENT_FN_WRITEOUT must be defined
-  to 1 to activate this feature. The endpoint number can be found in the
-  global variable 'usbRxToken'.
-- One default interrupt- or bulk-in endpoint. This endpoint is used for
-  interrupt- or bulk-in transfers which are not handled by any other endpoint.
-  You must define USB_CFG_HAVE_INTRIN_ENDPOINT in order to activate this
-  feature and call usbSetInterrupt() to send interrupt/bulk data.
-- One additional interrupt- or bulk-in endpoint. This was endpoint 3 in
-  previous versions of this driver but can now be configured to any endpoint
-  number. You must define USB_CFG_HAVE_INTRIN_ENDPOINT3 in order to activate
-  this feature and call usbSetInterrupt3() to send interrupt/bulk data. The
-  endpoint number can be set with USB_CFG_EP3_NUMBER.
-
-Please note that the USB standard forbids bulk endpoints for low speed devices!
-Most operating systems allow them anyway, but the AVR will spend 90% of the CPU
-time in the USB interrupt polling for bulk data.
-
-Maximum data payload:
-Data payload of control in and out transfers may be up to 254 bytes. In order
-to accept payload data of out transfers, you need to implement
-'usbFunctionWrite()'.
-
-USB Suspend Mode supply current:
-The USB standard limits power consumption to 500uA when the bus is in suspend
-mode. This is not a problem for self-powered devices since they don't need
-bus power anyway. Bus-powered devices can achieve this only by putting the
-CPU in sleep mode. The driver does not implement suspend handling by itself.
-However, the application may implement activity monitoring and wakeup from
-sleep. The host sends regular SE0 states on the bus to keep it active. These
-SE0 states can be detected by using D- as the interrupt source. Define
-USB_COUNT_SOF to 1 and use the global variable usbSofCount to check for bus
-activity.
-
-Operation without an USB master:
-The driver behaves neutral without connection to an USB master if D- reads
-as 1. To avoid spurious interrupts, we recommend a high impedance (e.g. 1M)
-pull-down or pull-up resistor on D+ (interrupt). If Zener diodes are used,
-use a pull-down. If D- becomes statically 0, the driver may block in the
-interrupt routine.
-
-Interrupt latency:
-The application must ensure that the USB interrupt is not disabled for more
-than 25 cycles (this is for 12 MHz, faster clocks allow longer latency).
-This implies that all interrupt routines must either have the "ISR_NOBLOCK"
-attribute set (see "avr/interrupt.h") or be written in assembler with "sei"
-as the first instruction.
-
-Maximum interrupt duration / CPU cycle consumption:
-The driver handles all USB communication during the interrupt service
-routine. The routine will not return before an entire USB message is received
-and the reply is sent. This may be up to ca. 1200 cycles @ 12 MHz (= 100us) if
-the host conforms to the standard. The driver will consume CPU cycles for all
-USB messages, even if they address another (low-speed) device on the same bus.

-General Description:
-This file is the 12 MHz version of the asssembler part of the USB driver. It
-requires a 12 MHz crystal (not a ceramic resonator and not a calibrated RC
-oscillator).
-
-See usbdrv.h for a description of the entire driver.
-
-Since almost all of this code is timing critical, don't change unless you
-really know what you are doing! Many parts require not only a maximum number
-of CPU cycles, but even an exact number of cycles!
-
-
-Timing constraints according to spec (in bit times):

-General Description:
-This file is the 12.8 MHz version of the USB driver. It is intended for use
-with the internal RC oscillator. Although 12.8 MHz is outside the guaranteed
-calibration range of the oscillator, almost all AVRs can reach this frequency.
-This version contains a phase locked loop in the receiver routine to cope with
-slight clock rate deviations of up to +/- 1%.
-
-See usbdrv.h for a description of the entire driver.
-
-LIMITATIONS
-===========
-Although it may seem very handy to save the crystal and use the internal
-RC oscillator of the CPU, this method (and this module) has some serious
-limitations:
-(1) The guaranteed calibration range of the oscillator is only 8.1 MHz.
-They typical range is 14.5 MHz and most AVRs can actually reach this rate.
-(2) Writing EEPROM and Flash may be unreliable (short data lifetime) since
-the write procedure is timed from the RC oscillator.
-(3) End Of Packet detection (SE0) should be in bit 1, bit it is only checked
-if bits 0 and 1 both read as 0 on D- and D+ read as 0 in the middle. This may
-cause problems with old hubs which delay SE0 by up to one cycle.
-(4) Code size is much larger than that of the other modules.
-
-Since almost all of this code is timing critical, don't change unless you
-really know what you are doing! Many parts require not only a maximum number
-of CPU cycles, but even an exact number of cycles!
-

-General Description:
-This file is the 15 MHz version of the asssembler part of the USB driver. It
-requires a 15 MHz crystal (not a ceramic resonator and not a calibrated RC
-oscillator).
-
-See usbdrv.h for a description of the entire driver.
-
-Since almost all of this code is timing critical, don't change unless you
-really know what you are doing! Many parts require not only a maximum number
-of CPU cycles, but even an exact number of cycles!

-General Description:
-This file is the 16 MHz version of the asssembler part of the USB driver. It
-requires a 16 MHz crystal (not a ceramic resonator and not a calibrated RC
-oscillator).
-
-See usbdrv.h for a description of the entire driver.
-
-Since almost all of this code is timing critical, don't change unless you
-really know what you are doing! Many parts require not only a maximum number
-of CPU cycles, but even an exact number of cycles!

-General Description:
-This file is the 16.5 MHz version of the USB driver. It is intended for the
-ATTiny45 and similar controllers running on 16.5 MHz internal RC oscillator.
-This version contains a phase locked loop in the receiver routine to cope with
-slight clock rate deviations of up to +/- 1%.
-
-See usbdrv.h for a description of the entire driver.
-
-Since almost all of this code is timing critical, don't change unless you
-really know what you are doing! Many parts require not only a maximum number
-of CPU cycles, but even an exact number of cycles!
-*/
-
-;Software-receiver engine. Strict timing! Don't change unless you can preserve timing!
-;interrupt response time: 4 cycles + insn running = 7 max if interrupts always enabled
-;max allowable interrupt latency: 59 cycles -> max 52 cycles interrupt disable
-;max stack usage: [ret(2), r0, SREG, YL, YH, shift, x1, x2, x3, x4, cnt] = 12 bytes
-;nominal frequency: 16.5 MHz -> 11 cycles per bit
-; 16.3125 MHz < F_CPU < 16.6875 MHz (+/- 1.1%)
-; Numbers in brackets are clocks counted from center of last sync bit

-General Description:
-This file is the 18 MHz version of the asssembler part of the USB driver. It
-requires a 18 MHz crystal (not a ceramic resonator and not a calibrated RC
-oscillator).
-
-See usbdrv.h for a description of the entire driver.
-
-Since almost all of this code is timing critical, don't change unless you
-really know what you are doing! Many parts require not only a maximum number
-of CPU cycles, but even an exact number of cycles!

-;max stack usage: [ret(2), YL, SREG, YH, [sofError], bitcnt(x5), shift, x1, x2, x3, x4, cnt, ZL, ZH] = 14 bytes
-;nominal frequency: 18 MHz -> 12 cycles per bit
-; Numbers in brackets are clocks counted from center of last sync bit
-; when instruction starts
-;register use in receive loop to receive the data bytes:
-; shift assembles the byte currently being received
-; x1 holds the D+ and D- line state
-; x2 holds the previous line state
-; cnt holds the number of bytes left in the receive buffer
-; x3 holds the higher crc byte (see algorithm below)
-; x4 is used as temporary register for the crc algorithm
-; x5 is used for unstuffing: when unstuffing the last received bit is inverted in shift (to prevent further
-;    unstuffing calls. In the same time the corresponding bit in x5 is cleared to mark the bit as beening iverted
-; zl lower crc value and crc table index
-; zh used for crc table accesses
-
-;--------------------------------------------------------------------------------------------------------------
-; CRC mods:
-;  table driven crc checker, Z points to table in prog space
-;   ZL is the lower crc byte, x3 is the higher crc byte
-;	x4 is used as temp register to store different results
-;	the initialization of the crc register is not 0xFFFF but 0xFE54. This is because during the receipt of the
-;	first data byte an virtual zero data byte is added to the crc register, this results in the correct initial
-;	value of 0xFFFF at beginning of the second data byte before the first data byte is added to the crc.
-;	The magic number 0xFE54 results form the crc table: At tabH[0x54] = 0xFF = crcH (required) and
-;	tabL[0x54] = 0x01  ->  crcL = 0x01 xor 0xFE = 0xFF
-;  bitcnt is renamed to x5 and is used for unstuffing purposes, the unstuffing works like in the 12MHz version
-;--------------------------------------------------------------------------------------------------------------
-; CRC algorithm:
-;	The crc register is formed by x3 (higher byte) and ZL (lower byte). The algorithm uses a 'reversed' form
-;	i.e. that it takes the least significant bit first and shifts to the right. So in fact the highest order
-;	bit seen from the polynomial devision point of view is the lsb of ZL. (If this sounds strange to you i
-;	propose a research on CRC :-) )
-;	Each data byte received is xored to ZL, the lower crc byte. This byte now builds the crc
-;	table index. Next the new high byte is loaded from the table and stored in x4 until we have space in x3
-;	(its destination).
-;	Afterwards the lower table is loaded from the table and stored in ZL (the old index is overwritten as
-;	we don't need it anymore. In fact this is a right shift by 8 bits.) Now the old crc high value is xored
-;	to ZL, this is the second shift of the old crc value. Now x4 (the temp reg) is moved to x3 and the crc
-; 	calculation is done.
-;	Prior to the first byte the two CRC register have to be initialized to 0xFFFF (as defined in usb spec)
-;	however the crc engine also runs during the receipt of the first byte, therefore x3 and zl are initialized
-;	to a magic number which results in a crc value of 0xFFFF after the first complete byte.
-;
-;	This algorithm is split into the extra cycles of the different bits:
-;	bit7:	XOR the received byte to ZL
-;	bit5:	load the new high byte to x4
-;	bit6:	load the lower xor byte from the table, xor zl and x3, store result in zl (=the new crc low value)
-;			move x4 (the new high byte) to x3, the crc value is ready

-General Description:
-This file is the 20 MHz version of the asssembler part of the USB driver. It
-requires a 20 MHz crystal (not a ceramic resonator and not a calibrated RC
-oscillator).
-
-See usbdrv.h for a description of the entire driver.
-
-Since almost all of this code is timing critical, don't change unless you
-really know what you are doing! Many parts require not only a maximum number
-of CPU cycles, but even an exact number of cycles!

-;nominal frequency: 20 MHz -> 13.333333 cycles per bit, 106.666667 cycles per byte
-; Numbers in brackets are clocks counted from center of last sync bit
-; when instruction starts
-;register use in receive loop:
-; shift assembles the byte currently being received
-; x1 holds the D+ and D- line state
-; x2 holds the previous line state
-; x4 (leap)  is used to add a leap cycle once every three bytes received
-; X3 (leap2) is used to add a leap cycle once every three stuff bits received
-; bitcnt is used to determine when a stuff bit is due
-; cnt holds the number of bytes left in the receive buffer

-General Description:
-This header is intended to contain all (or at least most of) the compiler
-and library dependent stuff. The C code is written for avr-gcc and avr-libc.
-The API of other development environments is converted to gcc's and avr-libc's
-API by means of defines.
-
-This header also contains all system includes since they depend on the
-development environment.
-
-Thanks to Oleg Semyonov for his help with the IAR tools port!
