Yes, I've received a prototype 6 weeks ago and have been working on the 
driver since then. I think I gave enough hint on this mailing list.

it uses bulk and control messages and requires a challenge response 
authentification. See http://www.grunau.be/riddle.txt if you want to 
help. The first two hex values are the challenge, the second two the 
response. The algorithm doesn't look well thought: byte 4 and seven of 
the response are always the same and up to 16 bits don't change the 
response if they are toggle.

I'll clean the current driver up tonight and make it available. It's not 
useless since the device still works after init under windows as long 
as it stays powered.
