  14 * and reworked.
  15 * 
  16 * Supported devices:
  17 *
  18 * - Standard 1 button mouse
  19 * - All standard Apple Extended protocol (handler ID 4)
  20 * - mouseman and trackman mice & trackballs 
  21 * - PowerBook Trackpad (default setup: enable tapping)
  22 * - MicroSpeed mouse & trackball (needs testing)
  23 * - CH Products Trackball Pro (needs testing)
  24 * - Contour Design (Contour Mouse)
  25 * - Hunter digital (NoHandsMouse)
  26 * - Kensignton TurboMouse 5 (needs testing)
  27 * - Mouse Systems A3 mice and trackballs <aidan@kublai.com>
  28 * - MacAlly 2-buttons mouse (needs testing) <pochini@denise.shiny.it>
  29 *
  30 * To do:
  31 *
  32 * Improve Kensington support.
  33 * Split mouse/kbd
  34 * Move to syfs
