Fail to scroll content with trackpoint and middle button.

Steps to reproduce:

1. hold the middle button (should be on center-top area, since it's button-less touchpad)
2. move the trackpoint

Actual results:

nothing move, tried using xev to capture information but nothing return.

Expected result:

Content/page should scroll as TrackPoint move around.
