I am using a logitech elite keyboard le and a logitech quick cam when i plugin the web cam the keyboard no longer works, i havent a clue what could cause this problem
If the keyboard and the webcam are both USB (meaning the keyboard isnt the other kind of plug [P/S2]) there could be a bus conflict between the two devices. My easy fix to this would be if you have a P/S2 adapter for your keyboard, use that with the keyboard and there shouldnt be a conflict. If you don't, try reinstalling the drivers for teh webcam and (if included) the keyboard also. Hope this helps. Best wishes.
