I have a P4 system with 4 USB ports. I had Win 2000 Pro before now when I upgraded to Win XP it stopped working. What might have happened to the USB ports.
USB Port is not working.

Right click MY COMPUTER>MANAGE>DEVICE MANAGER>USB CONTROLLERS.
Are the drivers properly installed? If not install them.
You may find them on your mobo cd.
That should help.
I suppose u have upgraded yourself but win 2000 was installed by someone else.
Install SP2 and there should be no problem the the USB ports.
