cannot resume using USB keyboard/mouse

When I suspend my desktop box, I cannot resume again by pressing a key 
on my USB keyboard or clicking a button on my USB mouse.  I have to 
press the chassis power button to wake things up again.  (I'd expect 
this to be necessary after hibernation, but not after suspend.)  The 
same machine resumes from suspend using keyboard or mouse buttons under 
Vista, so I know this is something that the hardware is capable of.

Is this a bug?  Or is there some local configuration tweak I should be 
making to tell the system to wake up in response to USB key presses & 
mouse clicks?

I'm running Fedora 8, with a Fedora-provided kernel version 
2.6.23.1-49.fc8.  Attached below is a pruned-down hardware description 
(from lshw) showing the mouse and keyboard, plus other buses and bridges 
by which they are connected.  Are there any other useful details I can 
provide?

Thanks!
