I believe I already set this to max and saw nothing regarding the
buttons.  

This is why I asked about debugging SCSI and getting verbose output with
SCSI.  Even though I have selected verbose/debugging w/i the kernel, I
still can't set SCSI debugging via /proc

Well, at least I know the buttons aren't actually working, but it's nice
to at least see a template within the code.  Anyways, still would like
to see if I can't get a memory address dumped from SCSI.  From my
guessing, the UMAX scanner probably sends out a signal through the scsi
(and USB if connected), when a button is pressed.
