 [[BR]]I see this also.  Under normal circumstances, a key on the USB
 keyboard will be picked up.  Not worth keeeping this ticket open.

 Was unable to reproduce the problem when keeping the ethernet busy with
 'rsync'.  But did reproduce the original problem at least once with os49
 and 'yum':  Did 'yum clean all', then 'yum check-update'.  Tried pressing
 on the USB keyboard at various time-offsets from when the screen had
 dimmed.  Usually, the screen did brighten.  But at least once I did happen
 upon a specific time-window when the USB bus was still powered up, but
 keypresses from the USB keyboard no longer caused the screen to brighten
 (an on-screen progress bar was still getting longer) -- after a few
 seconds, the CPU suspended (blinking power light) and the USB bus dropped
 power.  It would be unusual for users to encounter this combination of
 events.
