Scanner/Camera Device Install as Unknown
Recently, when installing any imaging hardware (i.e. scanner, camera, webcam, etc.) under Windows XP, they have started installing as an "Unknown Device" within the Device Manager instead of under "Imaging Devices".
They also do not show up under the Control Panel "Scanners & Cameras" and the "Add an Imaging Device" wizard no longer does anything.
I have reinstalled the devices numerous times and I have tried fixing my Window's XP install with the original XP install CD. Nothing changes.
Any ideas on what to try next short of wiping the hard disk and starting from scratch??
