The dmesg log for the auto-resume which you posted earlier shows that the resume completed successfully. Note BTW that your guess is impossible. In fact, the UHCI hardware doesn't even allow turning off the power to the port!

I don't know of any problems in the resume code. If you think there are some, try attaching other devices to that port and see what happens when you suspend and resume them.
