Read up on the xinput tool, run the xev program and see what the scroll
wheel is actually telling X, then see if you can come up with an
xinput command to fix it. If that works, then make a script named
something like /etc/X11/xinit/xinitrc.d/99-fixmouse.sh and put
the commands in there, and they will run every time anyone starts
a new X session. Here's mine to remap some buttons and enable
drag lock on my trackball:

xinput --set-button-map \
       'Kensington      Kensington Expert Mouse' \
       1 8 3 4 5 6 7 2
xinput --set-int-prop \
       'Kensington      Kensington Expert Mouse' \
       'Evdev Drag Lock Buttons' 8 2 1

Of course, if you use a KVM switch that has the effect of
unplugging and replugging the mouse, it gets more complicated
and you have to rerun the xinput commands every time you
plug in the mouse.
