+ * 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.
+ * Split mouse/kbd
+ * Move to syfs
