X11 mouse driver and USB mouse disconnection

[Scott Spare]

One interesting side effect: top reports continual high CPU usage (>65%) on
the Xorg process for many minutes after the mouse unplug-replug event.  I
haven't left it alone for long enough to see whether it ever dies down, but
can confirm it sticks at around 65% for 10 minutes.  Interestingly, the CPU
usage drops to single digits when I switch to a console virtual TTY then
switch back to Xorg.  No other programs are running from within X.

Here's a full unplug-replug event from Xorg.0.log:


(**) USB-PS/2 Optical Mouse: Device: "/dev/ums0"
(==) USB-PS/2 Optical Mouse: Protocol: "Auto"
(**) USB-PS/2 Optical Mouse: always reports core events
(**) Option "Device" "/dev/ums0"
(==) USB-PS/2 Optical Mouse: Emulate3Buttons, Emulate3Timeout: 50
(**) USB-PS/2 Optical Mouse: ZAxisMapping: buttons 4 and 5
(**) USB-PS/2 Optical Mouse: Buttons: 9
(**) USB-PS/2 Optical Mouse: Sensitivity: 1
(II) XINPUT: Adding extended input device "USB-PS/2 Optical Mouse" (type:
MOUSE)
(II) USB-PS/2 Optical Mouse: SetupAuto: hw.iftype is 5, hw.model is 0
(II) USB-PS/2 Optical Mouse: SetupAuto: protocol is SysMouse
(WW) fcntl(24, O_ASYNC): Inappropriate ioctl for device
(II) UnloadModule: "mouse"

I'll see if I can find anything else.  Thanks once again - this is the
closest this has been to working in quite a while.
