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

44 * The initial Wii Remote provided a bunch of buttons that are reported as
45 * part of the core protocol. Many later devices dropped these and report
46 * invalid data in the core button reports. Load this only on devices which
47 * correctly send button reports.
48 * It uses the shared input device.
