| 11 | * Wiimote Modules |
| 12 | * Nintendo devices provide different peripherals and many new devices lack |
| 13 | * initial features like the IR camera. Therefore, each peripheral device is |
| 14 | * implemented as an independent module and we probe on each device only the |
| 15 | * modules for the hardware that really is available. |
| 16 | * |
| 17 | * Module registration is sequential. Unregistration is done in reverse order. |
| 18 | * After device detection, the needed modules are loaded. Users can trigger |
| 19 | * re-detection which causes all modules to be unloaded and then reload the |
| 20 | * modules for the new detected device. |
| 21 | * |
| 22 | * wdata->input is a shared input device. It is always initialized prior to |
| 23 | * module registration. If at least one registered module is marked as |
| 24 | * WIIMOD_FLAG_INPUT, then the input device will get registered after all |
| 25 | * modules were registered. |
| 26 | * Please note that it is unregistered _before_ the "remove" callbacks are |
| 27 | * called. This guarantees that no input interaction is done, anymore. However, |
| 28 | * the wiimote core keeps a reference to the input device so it is freed only |
| 29 | * after all modules were removed. It is safe to send events to unregistered |
| 30 | * input devices. |

| 1285 | * on balance boards. |
