Fix the mouse question again to only run the mouse menu if a user doesn't

Fix the mouse question again to only run the mouse menu if a user doesn't
have a USB mouse.  Here's the deal on how this works:  USB mouse have
moused run for them automatically by usbd so we don't need to setup moused
for them.  We do need to setup moused for other mice though, so if the
user has a USB mouse, we don't need to do anything.  Hence the wording
"Do you have a non-USB mouse installed?" for the question.  The question
can be reworded as "Do you have a PS/2 or Serial mouse installed?" instead
if that is preferred.
