--- Comment #15 from Peter Hutterer <peter.hutterer at who-t.net> ---
The touchpad-edge-detector will give you the correct rules for what you
measured, but sometimes the kernel e.g. announces 1350:5630:30 and you measured
1349:5629:40. In that case, changing the min/max values (the first two values)
isn't necessary, the real ones are close enough. Only the resolution is off by
some significant factor, so the udev rules becomes merely ::40 (i.e. only
overwriting the resolution).

please, try to spend the time and effort in collecting data that's useful to
act on. I can't fix bugs based on guesswork. I don't mind if you take a day
longer to reply, but without data I can't do anything and I can't guess what
your touchpad does.
