Had a similar problem. Turned on my iMac and the keyboard will not function, no light on the mouse. This happened in both USB ports. I tried the keyboard and mouse on another computer, and they worked fine. The tower and flat panel seem to be functioning as well, so it appears to be the USB ports that are not working.
Came home and my computer was off after leaving it
on. Rebooted and now the keyboard won't do anything,
the ext. hard drive won't start. I can't insert the
repair disk because the keyboard won't operate.
Hmmm, what do you think I should try?

Hello Billch, et. al.,
I had a similar experience and what fixed it for me was actually unplugging the machine (not just powering off or restarting) and leaving it unplugged overnight. This seems to force the USB hub to reset itself.
You might also try pressing the the RESET button which is located under the base (you'll need to remove 4 screws), if you're not sure how to access the reset button just look it up in the support section and they will walk you through it with pictures and everything.
