I don't know if there is a disc that is specific for testing the controller, but there is a hardware test disc that tests out the various internal hardware, and I think might check the controller as well. I believe Atreyu has ripped this disc and provided a link to it in a thread in the unreleased games section on assemblergames.
Also, I recall AdamKoralick doing a youtube video on this disc in the last 2 or 3 months, so you can check that out for the name of the disc/program, and to see its capabilities in action.
