dmesg | grep .hid
ezbook 3 pro, apollo lake, ubuntu 16.04/17.10, out of the box touchpad doesn't work. With the v4.14-rc7 movement were tracked but not the phisical click of buttons. With the v4.14-rc8 trackpad is dead.

I have the ezbook 3 Pro (v4). With Manjaro Xfce 17.05 the touchpad does not work at all, but using Antergos 17.09 the touchpad works perfectly.

Dmesg logs for both non-working and working config's can be found here:

partially working touchpad 4.14.0-041400rc7
This is the dmesg of my ubuntu 16.04 installation with the 4.14.0-041400rc7 kernel. It has the trackpad working but not its left/right buttons.
After this kernel mainline release, the touchpad is not working at all.
There is a potential patch (quirk) for this. Please test it, if possible:
Ubuntu 16.04, Jumper ezbook 3 pro V4: patch is not working.
Compiled by myself with this patch 4.14.0-041400 and tried a kernel compiled by a more pro user than me (here. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1728244).
Touchpad is not working. The only semi working kernel is the 4.14.0-041400rc7 on mainline. Yes MOVING, Yes doubletap for clic, No buttons.

@mogio, I just noticed this in your dmesg log.
"random: fast init done"
If it means you have "fast boot" enabled in your BIOS you should disable that.
Mogio, see this patch. It looks related to your button click problem perhaps: https://patchwork.kernel.org/patch/10070339/
4.15 is a big no. Latest drm-intel-next 4.15 hasn't the touch-pad movement working. Rolled back to the 4.14...
@mogio a guy on the TT forum says that 4.15 did not work for him but rolling back to 4.14.3 did. I'm not sure but I think he's using Ubuntu. 4.14.3 has also been working for me without failure (so far). Manjaro just released 4.14.5 so I will be upgrading and testing that out soon.
Same problem here on Chuwi LapBook Air
touchpad showing as ALPS0001:00 0911:5288 Touchpad
tried kernels 4.14.14 through 4.15.1 including discussed patches and all no goor on Arch Linux.
I have magaed to bodge the touchpad to work by constantly removing and re-adding the driver using modprobe but on first suspend, if the touchpad is enabled, my system crashes.
Any news would be helpful.
just wait 4.16 and see if all hid patches fixed the issue.

4.14, 4.15, 4.16... still not working.
From ubuntu mainline...
the last semi working touchpad (movements are ok, physical buttons are not working) is the drm-intel-next 4.14.0-997.201712022100. After this: kaput. :)
