usb extended keyboard not recognised

My apple usb extended keyboard is no longer recognised by my iMac.


I experienced the same problem last year and was able to fix it by restarting in safe mode, and then restating again. This time, that remedy does not work.


I don't know whether this is relevant, but if I look at the system report the serial number of the keyboard is shown as "000000000000".


iMac 27″, 12.6
