In the device manager the devices are only shown when hidden devices are displayed. Both devices have a yellow exclamation point and error code 24 in details (device not present or not working). Replacing the drivers with a compatible one does not help.
A similar problem in is in the following thread, but for windows XP: Laptop Keyboard Not Working
There the problem was solved by reinstalling windows. Is there any quicker solution?
