 When I remove '/etc/ohm/inhibit-idle-suspend', the XO eventually suspends
 (power light pulsing very slowly).  When I resume by pressing a key on the
 XO's (green, builtin) keyboard, power is restored to my attached USB
 devices.  However, while my USB keyboard and my USB ethernet adapter
 function again (both are plugged directly into the XO), my USB mouse and
 USB CD-ROM (both are plugged into an USB hub) now do not function.  [This
 is a regression.  I do not remember which build still allowed USB-hub-
 attached devices to function following suspend/resume.]

 --------

 Took 'olpc-log' dump.  With /etc/ohm/inhibit-idle-suspend removed, it took
 nearly an hour for the dump command to complete (normally it takes several
 minutes).  While the 'olpc-log' command was running, the screen on the XO
 would dim (as it does for suspend) but would immediately brighten again --
 the XO's power light remained lit the whole time (it did not go into slow
 pulsing as it does for suspend).
