*
* Supported devices:
*
* - Standard 1 button mouse
* - All standard Apple Extended protocol (handler ID 4)
* - mouseman and trackman mice & trackballs
* - PowerBook Trackpad (default setup: enable tapping)
* - MicroSpeed mouse & trackball (needs testing)
* - CH Products Trackball Pro (needs testing)
* - Contour Design (Contour Mouse)
* - Hunter digital (NoHandsMouse)
* - Kensignton TurboMouse 5 (needs testing)
* - Mouse Systems A3 mice and trackballs <aidan@kublai.com>
* - MacAlly 2-buttons mouse (needs testing) <pochini@denise.shiny.it>
*
* To do:
*
* Improve Kensington support.
