Comment 5 for bug 126897

Hello,

First, kernel:

fabio@morpheus:~$ uname -a
Linux morpheus 2.6.20-16-generic #2 SMP Thu Jun 7 20:19:32 UTC 2007 i686 GNU/Linux
fabio@morpheus:~$ cat /proc/version_signature
Ubuntu 2.6.20-16.29-generic
fabio@morpheus:~$ dmesg | tail -n 8

Second, relevant Xorg Configuration lines:

Section "InputDevice"
        Identifier "HID 04b3:3108"
        Driver "evdev"
        Option "SendCoreEvents" "true"
        Option "Name" "HID 04b3:3108"
EndSection

and relevant log lines, after hot plugging the device:

Please note that I tried all sort of combinations listed on evdev(4) to make horizontal scroll work (as I did for my Microsoft Comfort Optical Mouse 3000 and worked perfectly after figuring out the mapping). Even brute force method to remap buttons... I said above about 17 buttons because in some weird configuration, it got those ghost buttons... I guess it was with the mouse driver, not evdev (I tried both).

And finally, I tested it on the latest 7.10 version and it still does not work. Also, when I press the vertical scrolling a little harder, it suddenly stops working. I remember finding (google) some other users claiming of the same thing. This behavior is not seen at Feisty with the above configuration. The live CD seems to let a generic mouse driver configuration only.

AFAIK, it should be fixed at kernel level, I can not see why this bug is attached to xorg.

Thank you.
