Title:
Elantech Touchpad detects as PS/2
As you can see from the logs above I've just booted on mainline kernel

Weird. The comment #7 shows it uses v4.13 but the dmesg you collected
was under v4.10.
Can you try mainline kernel? Currently it's v4.15-rc7.

Here is what I was able to collect running Ubuntu from external USB HDD.
The touchpad is currently working but it's a rather random issue that

If you need more info please do not hesitate to request it.

Ok, so I'm now using 4.9.0-040900rc1-generic kernel. For a hour or so I
thought that everything is good but then touchpad stopped working for a

xinput.
I added a kernel-bug-exists-upstream tag.
** Changed in: linux (Ubuntu)
Sure, I'll test it ASAP
