        that is not recognized by netbsd.
        The reason is, that it identifies itself as a pointer device and not
        as a mouse. I do not know what the difference between a pointer device
        and a mouse device should be, but the appended patch fixes the problem
        for me. But it might still be very wrong...

>How-To-Repeat:
        Try to use a mosart wireless mouse
>Fix:
        apply this patch:
