check that 
- you have permissions to read /dev/input/event*
- ID_INPUT **and** ID_INPUT_MOUSE/ID_INPUT_KEYBOARD is set on the input
  devices

if you're using libinput (judging by the error msg you do) it doesn't
actually care about ID_SEAT **unless* you want it to work on a specific seat
other than seat0.
