We plugged the keyboard into my laptop and it works fine.

I don't get it.

OK, one more time. I switched into my account on the wife's computer,
and the keyboard works! So I've setup a new account for her, and it
works there. That means that all her account-specific setting are
unavailable, of course, but at least the thing works.

Can anybody think of an account-specific setting that would disable
the keyboard?
