i have 8 unknown devices in device manager under imaging devices. and i can't uninstall them all i can do is disable them. when i try to uninstall i get "failed to uninstall the device. The device may be required to boot up the computer. i have been trying to get my old canoscan fb620u scanner to work. how can i get rid of those unknown devices?
Uninstall the scanner (or install it with proper drivers) then try deleting them. Also consider some of the other options in msconfig.exe such as selective start up.
ok that got rid of 6 unknown and now the scanner works but i still have 2 unknowns. when i checked thier properties it said it was a conon driver but that its not installed?
