I have a dell insprion 1100 laptop. When I plugged my ipod up via the usb port nothing would happen. It would not recognize the ipod. It would not recognize any kind of flash drive either. But my usb camera and a different mp3 player would work just fine. I uninstalled the usb ports and now I can not get them reinstalled. I have tried to reinstall the drivers through the device manager but it would not work. Any suggestions? Thanks.
