EV_ABS events, but it is possible that the module reports that it can
do relative events as well. Do you know what I should be looking for
to see if the kernel reports that it can do relative movements?
Can I somehow force the evdev driver to only accept absolute events?
I'll see if I can find the time to look into fixing the issue, as I
guess it could be related to my problems. But like everybody else I'm
in lack of time, so I'm not sure if it'll be doable.
