I will turn it OFF, if ON. I just recompiled the drivers with USB debugging
turned ON and I tried it on a machine that works. There are few enough
debugging messages so I will be able to copy off the screen. I now need
to wait in line to use the machine (about an hour or so), then I will
get back to you.

Any keyboards I have tried including the Dell keyboards we have laying
all over the place. I even tried an Apple keyboard because they are
different. I didn't expect to "work," only to be recognized as a keyboard.
