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.
