Title:
  Touchpad not recognized in Ubuntu 14.04 on Asus K501UX-AH71

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I just did a fresh install of Ubuntu 14.04.3 on my ASUS K501UX-AH71.
  Everything seems to be working fine, although a little buggy now and
  then. The main problem now is that the touchpad is not being
  recognized and is does not appear in /proc/bus/input/devices. External
  mice function fine.

  Reloading the mouse drive like below does not work:
  sudo modprobe -r psmouse
  sudo modprobe psmouse proto=imps

  Attached are dmesg, and I've pasted below two other outputs (only one
  attachment allowed):
