NOTHING I have hooked up to a USB port works, the computer doesn't recognize anything in a USB port. The devices work when plugged into a different computer, so it's not the peripherals. The optical mouse, for example, has power ( the light comes on), but nothing moves. Any suggestions?

Check the BIOS to see if USB connections are enabled there. If not, enable them and you should be set. If you have problems getting into BIOS, post the model number and brand of your motherboard here...or if you have a Dell/HP/Gateway etc, post the model number here and I'll help you get into BIOS...

Hi, ive got the exact same problem as Kranzberry. this also means that there is no way to use either my mouse or keyboard.
I have a Dell Dimension 9150
it would be great for any help thx

is it vista?

usb mice are screwed up in vista

no i running on xp

my usb ports dont work there enabled in bios I checked I dont know what to do its driving me crazy

maybe the usb ports hardware is at fault.

I wanted to set the USB port but I can't select the LegacyUSB Suport or USB Mass Storage. Any help.

my mice suddenly stop response in the middel of work in vista .

try checking the power option settings of your computer? had a similar problem before on my laptop computer and I tried a lot of things but nothing worked until I called support, the tech had me check my computer's power settings and found out that it is set to turn off or suspend the power on my USB ports if left for sometime, similar to what it does to the monitor I think, he had me change a few things and it worked well after that. Check if you have the same option in your computer, I don't recall the steps and the computer I have right now does not permit to go to control panel, if you want step by step instructions, try calling this number 1-877-7878749, I forgot their name but they might be of help.
