 I'd _guess_ - from a quick glance - that in your case the middle
 button "belongs" to the pass-through device (the stick, or whatever),
 so it's mapped by the driver's code to 0x40, while whoever wrote that
 code had their middle button belong to the main device, so it would
 have been mapped to 0x02.  The code in the else branch merged the two
 sets of buttons, but the scrolling code didn't and only tested the
 main device bits (and your kludge was to test the pass-through device
 bits).  So kre's fix is to always merge the buttons, and the scrolling
 code should now react to both the primary and the pass-through middle
 buttons.
