OK.  Thanks.

Come to think of it, there a few bigger issues to solve first.  For
now, I suggest ignoring my comment about
BTN_TOOL_MOUSE+BTN_TOOL_FINGER being in proximity at the same time and
just get stylus+pad buttons working without addressing.  Or at least
put it to back of your head. :-)

The issue is that right now, Protocol 5 devices have to be manually
added to a list in xf86-input-wacom so probably this bluetooth device
is treated as a Protocol 4 device.

One difference is serial # for PAD device is 0xff vs. -1 between the
two protocols so xf86-input-wacom will chose wrong channel if it
thinks its a Protocol 4.  The xf86-input-wacom logic could stand to be
rewritten to compute all channel #'s like it does for Protocol 5's
(look up an unused slot and ignore exact serial # value).

The ABS_DISTANCE also becomes very important for mice pucks and
Protocol 4 vs. 5 currently send it with inverse meaning.  And nothing
from kernel side advertises Protocol 4 vs. Protocol 5.  Thus the hard
coded list. Opps.

Protocol 4 doesn't give you anything beyond what we've come to call
Protocol Generic (simple tablets) so I've pushed to end-of-life
Protocol 4.  Since we do not have generic replacements for Protocol 5
concepts yet, it will need to stay around for a while.  Maybe we
should change default in xf86-input-wacom for unknown tablets with
serial #'s from Protocol 4 to Protocol 5?
