 *
 * This program demonstrates the use of libusb to communicate with CC-USB.
 * The prerequisites are:
 * (i) EHCI driver installed - it is part of newer distributions of Linux
 * (ii) libusb package installed - it is installed automatically by newer 
 * distributions (I amd using Mandriva 10.2).
 *
 * The program calls first usb_init(), usb_find_busses(), and usb_find_devices(),
 * passing relevant arguments to structures bus and dev.
 * 
 * compile as:
 * gcc -o flahvmusb flashvmusb.c -I/usr/local/include -L. -Insl -lm -lc -L/usr/local/lib -lusb
