- * 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.
