* - 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 <[email protected]> |
|
* - MacAlly 2-buttons mouse (needs testing) <[email protected]> |
|
* |
|
* To do: |
|
* |
|
* Improve Kensington support. |
|
* Split mouse/kbd |
