Public bug reported:

Binary package hint: xserver-xorg-input-evdev

This is a new bug since a clean install of Ubuntu Natty. It is a
regression since I didn't encounter this behaviour with any previous
version of Ubuntu.

On first boot, plugging in a USB keyboard and mouse directly to the USB
ports means they function well. However, after suspending and resuming,
the mouse and keyboard no longer send events to X. That continues even
after unplugging and replugging them into the same ports or different
ports or the hub. The only solution seems to be to reboot the system to
get back the use of external input devices.

WORKAROUNDS

Is there any way to force the reloading of device drivers or the USB
subsystem manually to get my devices back and prove that there is a
proper resume process which Natty is failing to trigger.

OTHER INFORMATION

I note two problems which apply even on the first boot but they are
relatively minor. Periodically the mouse pointer stops moving for a
second - this may be a resource starvation issue somewhere else in the
system. Also I seem to be unable to use a USB hub to connect the
keyboard and mouse which I have used successfully across about four
major versions of Ubuntu. However, this could also be a failure of the
hub so I'm leaving that for now. On the most recent occasion I
encountered this, there was a Kindle plugged in to charge over USB, but
removing it or replacing it after resume seems to have no effect on the
functioning of the keyboard and mouse, so I guess this is unrelated.
