The great @kaihengfeng in the bug 1688625 told me to do this, and with this
touchpad has worked partially:
sudo sh -c 'echo -n "elantech" > /sys/bus/serio/devices/serio2/protocol
Now if it works, but it works simply, without appearing as a touchpad in
the system and without working with 2 fingers (scroll not work) or with
3, now it moves but only with a finger and these are its properties:
$ xinput --list-props 12
