as usual it may be a little tricky and take some time to do the reverse 
engineering: you'll probably need to sniff the USB traffic using e.g. a 
tool like usbsnoop (http://usbsnoop.sourceforge.net/), maybe disassemble 
and analyze the windows to find out what has to be done to talk with the 
hardware. Basically the same had been done for most USB TV/DVB drivers 
without open docs.
