I think, the problem is with noloop parameter. X550L is added to quirk,
but yours was not.

Add "i8042.noloop=1" boot parameter.

Title:
  Touchpad detected as mouse on Asus ux303ln laptop

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” package in Arch Linux:
  New

Bug description:
  Hi! I'm following the bug reporting documentation here:

  https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_Touchpad_features_like_scrolling.2C_tapping.2C_etc._do_not_work_at_all.

  The touchpad on my new Asus ux303ln laptop is detected as a mouse, so
  I can't access touchpad features such as two-finger scrolling.

  The laptop was very recently released and I couldn't find any
  outstanding firmware updates for it through Asus's Windows-based
  tools.

  % lsb_release -rd
  Description:	Ubuntu 14.04.1 LTS
  Release:	14.04

  Per the instructions on the wiki, I'm attaching output from
  /proc/bus/input/devices,` xinput --list`, and /var/log/Xorg.0.log.

  This machine also has a touchscreen, which I'm fairly certain is the
  "maXtouch digitizer" visible in the logs. I haven't yet restarted in
  Windows to see if it says anything useful about the touchpad, but I
  can do so if that's helpful. This is a fresh install of 14.04 and I
  haven't done much customization of it apart from installing some
  applications and changing the default resolution.

  The only relevant bit I noticed in /var/log/dmesg is this:
