--- Comment #3 from Peter Hutterer <peter.hutterer at who-t.net> ---
What's missing here is the axis resolution. This one is required for tablets,
otherwise we cannot convert the dimensions to mm as libinput promises.

The product ID of the device is 0x01 so I suspect egalax is re-using usb ids.
That means we cannot ship this as a generic patch because it'll break other
devices. You'll need local configuration to set this for your device.

Best solution: locate 60-evdev.hwdb on your machine and follow the instructions
at the top to add a local copy of this file to /etc. The overrides you'll need
are EVDEV_ABS_00=::R1 and EVDEV_ABS_01=::R2, where R1 and R2 is the resolution
of the x and y axis, respectively, in units/mm. You get that number by
measuring the device and dividing the x/y ranges by the dimensions, in your
case R1 is 4010/width-in-mm, R2 is 3075/height-in-mm.
