-General Description:
-This is the host-side driver for the custom-class example device. It searches
-the USB for the LEDControl device and sends the requests understood by this
-device.
-This program must be linked with libusb on Unix and libusb-win32 on Windows.
-See http://libusb.sourceforge.net/ or http://libusb-win32.sourceforge.net/
-respectively.
