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

/*
 * Balance Board Extension
 * The Nintendo Wii Balance Board provides four hardware weight sensor plus a
 * single push button. No other peripherals are available. However, the
 * balance-board data is sent via a standard Wii Remote extension. All other
 * data for non-present hardware is zeroed out.
 * Some 3rd party devices react allergic if we try to access normal Wii Remote
 * hardware, so this extension module should be the only module that is loaded
 * on balance boards.
 * The balance board needs 8 bytes extension data instead of basic 6 bytes so
 * it needs the WIIMOD_FLAG_EXT8 flag.
