[Dell Latitude E5450] Touchpad is being recognized as ImPS/2 Generic Wheel Mouse

[Yung Shen]

In generally this touchpad works fine, however there is no touchpad related configuration shows in System Settings.

And secondly, middle button with Point stick scrolling is not working. This touchpad got five individual buttons, each of them is working, however only scrolling by using point stick with middle button is not working. config like this:

upper left | middle | upper right
[ touchpad ]
buttom left | buttom right

There is a temproary workaround can enable the scrolling, with following command:
$ xinput set-prop 14 "Evdev Wheel Emulation" 1 && xinput set-prop 14 "Evdev Wheel Emulation Button" 2
