Mathias-

Thanks for the quick work.  Despite the issues noted below, this is a
major improvement over psmouse.proto=bare, which was driving me insane
with the accidental touch-clicks while typing.  Thank you so much for
your quick response!

This kernel does allow the touchpad to be recognized but still seems to have some issues:  
1) Intermittently, the pointer stops responding to the current touch;  
   a) I can usually (~70%) replicate the behavior by moving the pointer into contact with the left side of the screen.  Once it touches that side, the current touch no longer changes the pointer position.  Lifting that finger and re-touching the pad starts the pointer moving again.
   b) I also see this behavior when the pointer is not near the screen edges, but is unpredictable, and in 30 minutes of testing, I haven't found a consistent pattern for replicating the issue.
 
2) the two finger scrolling does not exclude the button areas;  e.g. if I rest a finger on the primary button, I can no longer move the pointer, only scroll the screen.  In other touchpads I've used, the button area was excluded from two-finger scrolling issues.  This issue is less concerning than #1, but the experience is very unnatural.

Again, thanks for the fast response;  I'm happy to run any other tests
that you think might diagnose the issues.

Title:
  Touchpad detected as mouse on Asus ux303ln laptop

Status in linux package in Ubuntu:
  Fix Released
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:
