Initializes a touch device.
It will have 3 valuators: an "Abs MT Position X" at axis 0,
an "Abs MT Position Y" valuator at axis 1 and an "Abs MT Pressure" valuator
at axis 2.
It will have 5 valuators: an "Abs MT Position X" at axis 0,
an "Abs MT Position Y" valuator at axis 1,
a horizontal scroll valuator on axis 2,
a vertical scroll valuator on axis 3 and an "Abs MT Pressure" valuator
at axis 4.
