This mouse has been supported since XFree86 3.3.
However, support in 3.3.2 is slightly different;
the wheel movement is recognized as the Z axis motion.
This behavior is not compatible with XFree86
3.3, but is more consistent with the support for other mice with
wheels or rollers.
If you want to make the wheel behave like before,
you can use the new option "ZAxisMapping"
as described above.
IntelliMouse supports the PnP COM device specification.
