[kendatsuba <bugs.kendatsuba@xxxxxxxxx>]

Unfortunately, even if the driver complains of an unknown hardware
version, the firmware version of the touchpad is not mentioned in the
emitted error message:

[ 18.453420] psmouse serio1: elantech: unknown hardware version,
aborting...

The module contained in the attached dkms package should print the
firmware version along with the error message. By knowing the firmware
version, it will be possible to force the recognition of the touchpad
and see if the structure of the packets is the same used by one of the
already supported firmwares.

Here are the steps you must follow:

sudo dkms ldtarball psmouse-elantech-show-version.tar.gz
sudo dkms install -m psmouse -v elantech-show-version

sudo rmmod psmouse
sudo modprobe psmouse

and post the output of the following command:

dmesg | grep elantech

When you're done don't forget to remove the module:

sudo dkms remove -m psmouse -v elantech-show-version --all
