I have a Toshiba Satellite A65-S1062 notebook. Model No. PSA60U-01W015. It came with XP Home, I upgraded it to XP Pro. It is only two months old. The USB ports worked prior to the upgrade, they have not worked since the upgrade. There are no errors in Device Manager, the other ports I've used on the system work fine, mainly the LAN port. Device Manager lists Standard Enhanced PCI to USB Host Controller, Standard OpenHCD USB Host Controller twice and USB Root Hub twice. The Device Manager does say that "No Drivers are Installed" for any of these devices. I searched Toshiba's support site for the unit and was unable to locate the driver. The driver did not install from the hard drive either. Any assistance on this would be appreciated. Thank you in advance.
