Comment(by mikus):

 Replying to [comment:1 cjb]:
 > I'd be interested to know what additional lines appear in dmesg as you
 unplug and replug the USB hub into the XO after resume.  (Does that fix
 it?)

 What I did: Remove /etc/ohm/inhibit-idle-suspend;  Reboot;  Launch
 Terminal;  Move mouse - cursor moved;  Wait for suspend, and let it sit
 some seconds; Press <shift> to wake up XO.  Touch /etc/ohm/inhibit-idle-
 suspend;  Move mouse - cursor did not move;  Unplug USB hub, and let it
 sit some seconds;  Plug in USB hub, and capture 'dmesg' output;  Repeat
 unplug / replug of USB hub (and capture 'dmesg' output).

 Result: 'dmesg' did NOT show anything upon unplug/replug of USB hub;
 Mouse movement continued to not affect cursor.
