Agressive USB autosuspend makes me lose keystrokes

[Martijn vdS]

I just upgraded to Oneiric alpha-1, and now my keyboard sometimes loses a keystroke.

I've tracked this down to USB autosuspend mode: by echoing "on" to "/sys/bus/usb/devices/2-1.3/power/level", the problem disappeared.

This still happens on current oneiric.

I have to do this quickly after every boot, or I risk losing my keyboard (until I unplug/replug it):

echo "on" > ./devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/power/control

I don't think there are ways to avoid the problem if you have to enable runtime
pm for usb input devices(kb, mouse).

Generally speaking, the first key you pressed is used to wakeup the usb keyboard
and the key is dropped by keyboard, then the driver can report the
subsequent keys
you pressed to input and application after the device leaves suspend state.

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel currently in the release pocket than the one you tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help.
