The disconnect problem is the exact same problem I keep getting. I've 
tried to ask on the linux-usb lists, but I was told that i "had faulty 
hardware if I keep getting disconnects" - I don't think so as a lot of 
us Nova-T users seem to be getting the exact same disconnect problem.

Hope someone comes up with a fix soon, or at least can help us figure 
out what's causing it!
