W2K Pro w/SP4, P3 dual processors. Wife plugged camera into front USB port, locked up PC, now all devices (scanner and camera) off and no USB front or back.

Checked System Device MGR and USB Root and VIA MB USB drivers - indicated working properly, acted like it wasn't connected so I changed cables. Re set CMOS on MB jumper. Went into safe mode and uninstalled USB Root and VIA USB. On reboot it found hardware and reinstalled, still no USB.

E mailed Tyan MB vendor. I had updated the BIOS which did have a USB slow ISSUE. Considering uninstalling the VIA USB drivers and reloading clean copies, then re flashing the BIOS.

Any suggestions would be appreciated.

Camera is a Fuji and drivers were already installed so when you plugged the USB port in and turned the camera on to send it automatically brought up the application.

when I went into control panel, SCANNERS and cameras, neither the scanner nor camera were listed as they had been before.
