This message means that the device has ID_INPUT_TABLET assigned but it
shouldn't. That's a udev issue, not sure why this happens though. Do you have a
manual override or something? same for th eothers

yes, P and T are Pad and Tablet capabilities. and from the evemu output at
least I can tell that the event sequence looks correct. libinput spits out a
whole bunch of tablet events too.
I recommend grabbing libinput from git and building with gtk+-3 devel headers
installed. that way you can run make and sudo ./tools/event-gui to test if the
tablet responds correctly.

libwacom is merely a descriptive library. it's used by GNOME but only to
display the config item. It doesn't decide if the tablet works otherwise.

if xsetwacom detects the device you assigned the wacom driver, not libinput.
change the Driver line to "libinput".

from the libinput output I get here you get proximity events. there's a tip up,
followed by axis events (though it doesn't move much) so proximity works. the
stylus buttons come in while the tip is up, so everything appears to work?
