+ * Wiimote Modules

+ * 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.
