Hello,
I found this regression w.r.t. 2.6.29.
When enabling usb automatic power management for all usb peripherals, with:
> for i in /sys/bus/usb/devices/*/power/level; do echo auto > $i; done

after 2 seconds of inactivity (my autosuspend threshold), the mouse
gets stuck under X.
Pushing a mouse button will revive it (and the event is passed to X).
Disabling automatic power management, with:
> for i in /sys/bus/usb/devices/*/power/level; do echo on > $i; done
removes the problem.

My kernel config is attached.

Thanks,
Corrado
