They won't be able to help, I can - but not for a few weeks.

I'm expecting to release public USB protocol information during Jan 08 
which would allow a GPL driver to be written. Right now I have nothing 
to give you.

If you feel adventurous, feel free to start now by reverse engineering 
the protocol with a windows software USB sniffer, it won't be wasted 
work. The device is Cypress FX2 based (which Linux has lots of examples 
for) and it loads custom firmware (which Linux has lots of examples of) 
apart from that I think the protocol is very simple.

How to integrate it with the kernel s/w demux would be an interesting 

Let me know if I can help.
