Bug description:
  This is a related but separate issue to bug #1480673  "Asus T300 CHI
  bluetooth Touchpad is recognized incorrectly".

  Affecting this digitizer is also bug #1574028 "Asus T300 CHI:
  touchscreen digitiser missing at boot".

  Using 16.04 amd64 Ubuntu (unity).

  In this case the USB-attached "Synaptics Touch Digitizer V04" fails to
  provide any multitouch functionality.
