Hi!
  Thanks for the tip with evtest, I didn't know about this program.
My "regular" vertical wheel causes the following reports when rotated:
(two steps both ways)
Event: time 1193410779.718397, type 2 (Relative), code 8 (Wheel), value -1
Event: time 1193410779.718399, -------------- Report Sync ------------
Event: time 1193410779.790386, type 2 (Relative), code 8 (Wheel), value -1
Event: time 1193410779.790389, -------------- Report Sync ------------
Event: time 1193410779.950366, type 2 (Relative), code 8 (Wheel), value 1
Event: time 1193410779.950369, -------------- Report Sync ------------
Event: time 1193410779.998354, type 2 (Relative), code 8 (Wheel), value 1
Event: time 1193410779.998356, -------------- Report Sync ------------


The horizontal wheel reports this:
Event: time 1193410781.070196, type 2 (Relative), code 8 (Wheel), value 1
Event: time 1193410781.070198, type 2 (Relative), code 9 (Misc), value 8
Event: time 1193410781.070200, -------------- Report Sync ------------
Event: time 1193410781.086188, type 2 (Relative), code 8 (Wheel), value 1
Event: time 1193410781.086189, type 2 (Relative), code 9 (Misc), value 8
Event: time 1193410781.086189, -------------- Report Sync ------------
Event: time 1193410781.310156, type 2 (Relative), code 8 (Wheel), value -1
Event: time 1193410781.310157, type 2 (Relative), code 9 (Misc), value 8
Event: time 1193410781.310159, -------------- Report Sync ------------
Event: time 1193410781.350150, type 2 (Relative), code 8 (Wheel), value -1
Event: time 1193410781.350151, type 2 (Relative), code 9 (Misc), value 8
Event: time 1193410781.350152, -------------- Report Sync ------------


So the reports are different, yes... But it seems that the horizontal wheel
reports the standard wheel event together with a misc event with value 8.
Is that correct ? Is the X11 mouse driver able to distinguish between them ?
I've tried both "mouse" (with /dev/input/mice) and "evdev" (with
/dev/input/event4) drivers and both seem to behave identically.
