USB Problems

After I restored my computer for some reason two of my usb ports refuse to work, I've got 4 but the bottom two won't work. I've installed USB 2.0 and the hardware works on the top two but not on the bottom. How do I get these working again? Thanks.

Install service pack1 first, if you haven't.  If it still doesn't work, remove all the USB devices, to be sure.

Have you checked that the on board usb is enabled in the bios?
also check that the lead is firmly plugged onto the motherboard.
The lower USB ports are usually connected via a cable to the mobo, unlike the top ones which are built in.

Yes USB is enabled I believe. I checked for something stating USB support and it was enabled. As for opening my computer up and plugging iin the lead, I'm not sure how to do that and I've never torn my computer open.

In device manager are there any red or yellow markers (exclamation marks or x's)?
if so remove them & reboot.
what appears in device manager for your USB?

You may need to remove the USB drivers in device manager even if they appear normal and reinstall them - if this is WinXP, they will reinstall on reboot.

From the Device Manager , Uninstall all the USB/Enhanced USB Root Hubs and USB Controllers.  Then Restart your computer. Most probably this should resolve the issue.

for more troubleshooting Click Start > RUN > Type services.msc and on the List of Service ensure that your Plug and Play is not stopped. If it is then start the service.

Hope that helps

I'm not sure I have installed Service Pack 1 yet, I'll do so. Which of these devices should I remove, though? All?
