Public bug reported:
Binary package hint: xserver-xorg-input-evdev
Evdev fails to correctly configure horizontal scrolling for the
Microsoft Comfort Mouse 4500.
Instead of buttons 6 and 7 a third axis (valuator 2) is recognized.
Pushing the scroll wheel to the left (right) causes a decrease
(increase) of valuator 2. No button event is shown in xev. Valuator 2
was associated to GAS. I think it rather should be associated to HWHEEL.
