Keyboard cannot be identified.
I never ran into this problem until recently, I own the Apple Keyboard with Numeric Keypad - English (USA) which is connected through the back of my imac USB port. The "Up" arrow key however no longer works, although the other arrow keys work.
Whenever I try to run the Keyboard Setup Assistant, I press the "z" key and a dialog appears saying ""your keyboard cannot be identified". Is there some form of troubleshooting or software/firmware that I can download to fix this issue??
Thank you so much!
iMac, OS X Mountain Lion (10.8.2)
