Reliable troubleshooting would start with a very expensive USB test setup to verify that the keyboard is working properly. At work, when some mouse, keyboard, display, etc. caused trouble, we would swap the suspect component with one that was working to see if the problem moved with the component. Maybe you could lend the keyboard to a friend for a test. -- George N. White III
