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.
