--- Comment #14 from Martin Kolman <martin.kolman at gmail.com> ---
So evemu-describe tells me the tablet has:

Input device ID: bus 0x03 vendor 0x8ca product 0x10 version 0x105

Based on that I've changed to local hwdb entry as follows (did I convert/write
the v and p values properly ?):

#########################################
# Trust
#########################################

# Trust Wireless Scroll Tablet TB-4200
# (Aiptek based ?)
evdev:input:b0003v8CAp10*
 EVDEV_ABS_00=::26
 EVDEV_ABS_01=::15

With this it seems to work the same as before, *but* it seems to work even if I
remove the file or use nonsencial values after v and p. Could be that the
previous name based rule persisted and is still being used ?

I'm using this to reload the local hwdb (while the tablet is discoonnected):

systemd-hwdb update
udevadm trigger /dev/input/event*

Then I attempt to connect the tablet.
