If scrollwheels are found, bump the button number by 4 (or up to 7).
Scrollwheel data is always posted as buttons, so we need to advertise at least
enough buttons to accommodate for 6/7 (horizontal wheel).
Note that this may mean that if you have a device that has scroll wheels and
axes, but no buttons, it may be interpreted as a mouse.
