Actually, I had applied your patch to be on the safe side, (that is, the change in hub.c from msleep(10) to msleep(20) before getting all of this to it's current state. I didn't test it before this change, so I'm not sure how much it affects it. > It may be some kind of timing bug, similar to what I see > with 1160 with some devices.

(Especially if in the interrupt handler, as it will take too much time and a new interrupt will fire by the time it exits; Or at least that's my limited understanding) I will try out various things, and let you know what I discover. Thanks for the hint! And thanks again guys, for all your help. It is appreciated!
