I had this problem on my computer at work, installing the USB drivers seemed to fix it.. Anyways I have the same problem but on another computer. My co-worker was hotsyncing several Palm TX's to his machine. Then about a day later when he went to connect a USB device, like a thumb drive or USB cd drive etc. they did not work. You can hear windows detect the device and you can see the safety remove icon in the task bar but they do not show up otherwise. For instance if you plug in the USB thumb drive you will not see it in My Computer, if you plug in the CD drive, you will also not see it as a new CD drive inside My Computer. What is very strange is that his Microsoft USB Mouse works fine, and the Palm TX still seems to sync fine. I had the same problem with my machine, Palm software worked, USB mouse worked, but all other devices that were required to show up in the OS didn't work. Reinstalling the USB drivers fixed the problems for me, but not for my co-worker. We have tried uninstalling all the USB drivers, tried installing the USB drivers in safe mode, nothing has worked.

All USB ports do not work, the 4 on the back of the motherboard don't work and the 4 in the front of the computer do not work. If anyone has experienced this problem can you please help?

Thanks a lot
 
Make sure you have the latest BIOS/Chipset drivers as well, I had a similar problem on one of my boxes and after the updates it seemed to go away.
 
i have foudn that if you remove a usb object without "ejecting" it, then nothing will show up when plugged into that usb port untill you restart the computer.. (more like 3 restarts in win2k).. that wouldn't explain all of them going. . but if one was.. i would look into that..
