Same here except that i'm doing it through the serial link.

I have some lost connections which usually last for about 3 seconds.

Ok, so here is my guess:
"IF" you happen to have a too short power supply on that computer this 
can cause the problem. I have a rather too small P.S. on my system: it 
works correctly most of the time but gives me some quirks from time to 
time. The serial link is that little bit too much for it, maybe the USB 
is the same for you. If you can test that with another P.S. more 
powerfull...

The fact that your driver dies and not mine is probably due to the 
differences between USB and serial... Maybe.
