I have the same problem but the ports are on a external hub. Are yours?
If not sounds like a driver conflict. Or simply bad internal hub. On a
laptop you are pretty much limited as what you can do. As for me
replacing the hub (external) with a higher quality one worked out. I did
once have the same problem with an Asus motherboard in a pc. Which Asus
replaced. But in your case if stripping and reinstalling windows doesn't
fix the problem (if it's internal ports) then the internal hub probably
went south. If it's that, then I have no idea other than replacing the
laptop since I doubt you laptop is still under warranty.

Wish I could give you better info.

I have 2 slightly aged Dell pc's that seem to boot up ok, but the usb
mouse and usb keyboard stop working after a couple of keystrokes on the
keyboard. I've tried different keyboards and mouse, same result.  Pulled
and reinserted the internal cards and memory, all of the usb ports have
the same issue. Both pc's are win xp with sp3, Optiplex GX270 and
Optiplex GX280. Paul Hachmeyer
