Title:
  Touchpad not recognized on Dell Latitude E7470 Ultrabook

Status in linux package in Ubuntu:
  Triaged
Status in xserver-xorg-input-synaptics package in Ubuntu:
  Confirmed

Bug description:
  Expected: Touchpad settings available in Mouse & Touchpad Settings
  dialog

  Actual result: Touchpad settings missing entirely

  
  Details:
  The touchpad on my Dell Ultrabook (Latitude E7470) functions mostly. 

  The settings for the touchpad are not available at all in the Mouse
  and Touchpad settings (see http://i.imgur.com/YRGiOrj.png).

  Two-finger scrolling works as expected except it's using "Natural
  Scrolling" by default and there is no way to change it.

  xinput list does not display a touchpad at all:

  ⎡ Virtual core pointer                        id=2    [master pointer  (3)]
  ⎜   ↳ Virtual core XTEST pointer                      id=4    [slave  pointer 
 (2)]
  ⎜   ↳ ELAN Touchscreen                                id=11   [slave  pointer

  /proc/bus/input/devices lists the device as a "Generic Wheel Mouse"
