--- Comment #3 from Alex Corcoles <alex at corcoles.net> ---
Thank you. However, I must admit I must be an idiot.

I am unable to create the selector for the trackpoint as:

# cat /etc/udev/hwdb.d/71-pointingstick-local.hwdb
evdev:input:*
  POINTINGSTICK_SENSITIVITY=200
  POINTINGSTICK_CONST_ACCEL=100.0

However, if I do:

sudo udevadm hwdb --update ; sudo udevadm trigger /dev/input/event1

I get the following in my logs:

, which doesn't look good and indeed doesn't do anything.

If there is some reading material on this I'd be happy to read it :(
