At that point the disconnect (or more generally, the connection-status change) is detected and everything goes back to normal. Your problem is caused by the fact that the connect-status changes do not cause the suspended root hub to wake up -- presumably because they don't cause the controller to generate an interrupt request. > If you would like me to, I can replicate that with a trace also. Not needed as far as I'm concerned. Sarah might want more information.
