Bug description:
  CID: 201402-14663 Dell Latitude 12 Rugged Extreme

  The touchpad on this system was recognized as a Wheel mouse,
  the vertical edge scrolling works, as well as the 2-finger vertical scrolling

  However, horizontal edge scrolling and 2-finger horizontal scrolling does not work.
  From the "Mouse & Touchpad" settings, there is no option for changing scrolling behaviour. (Screenshot attached)
