So I have been trying to get my USB ports to work with no luck. It's really weird, they worked one night and then stopped working by the next time I got to the computer. They are the rear usb ports on the back of my mobo which is a geforce 6100-m9. I plug my ipod into the ports and they charge the ipod so i know they have power but the comp doesn't recognize the ipod and connect to it along with my flash drive. I have unintalled the drivers and reinstalled them multiple times thinking I did it wrong and still no success. Anyone have any ideas?
