Hi All,

I've just bought a WOP-49 USB optical mouse.
Unfortunately I was not able to get
the 2nd wheel ("zoom wheel") working in XWindows (xorg, Debian GNU/Linux
testing).
All 5 buttons are reported correctly, and the first wheel is reported as
buttons 6 and 7, but second wheel does not work.

My xorg.conf pointer section is as follows:
Section "InputDevice"
 Identifier "USB Mouse"
 Driver "mouse"
 Option "AlwaysCore"
 Option "Device" "/dev/input/mice"
 Option "Protocol" "ExplorerPS/2"
 Option "Emulate3Buttons" "no"
 Option "Buttons" "9"
 Option "ZAxisMapping" "6 7 8 9"
EndSection

I have experimented with number of buttons (eg. I've set it to 12), but
no results.
In Windows XP both wheels work (however the second one does the same as
the first one - probably a special driver is required).
 
Has anybody succeeded to get both wheels working in this mouse?
