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.
