In my case I got a 4.15 kernel working in my jumper ezbook3 pro, ubuntu 17.10, the touchpad was detected as ImPS/2 protocol (so as an extended mouse) (enough for me), but after reinstall a ubuntu mate 18 (recent kernel) the touchpad is detected with CyPS/2 protocol and does not work at all.
Also affected.
