   driver, by Jiri Kosina
 - PS2/3 Buzz controllers support, by Colin Leitner
 - rework of wiimote driver including full extensions hotpluggin
   support, sub-device modularization and speaker support by David
   Herrmann

supported and if detected, it's no longer reported as static

device then.

Contact: David Herrmann <dh.herrmann@gmail.com>
Description: While a device is initialized by the wiimote driver, we perform
a device detection and signal a "change" uevent after it is
done. This file shows the detected device type. "pending" means
that the detection is still ongoing, "unknown" means, that the
device couldn't be detected or loaded. "generic" means, that the
device couldn't be detected but supports basic Wii Remote
features and can be used.
Other strings for each device-type are available and may be
added if new device-specific detections are added.
Currently supported are:
gen10: First Wii Remote generation
gen20: Second Wii Remote Plus generation (builtin MP)
balanceboard: Wii Balance Board
What: /sys/bus/hid/drivers/wiimote/<dev>/bboard_calib
Date: May 2013
KernelVersion: 3.11
Contact: David Herrmann <dh.herrmann@gmail.com>
Description: This attribute is only provided if the device was detected as a
balance board. It provides a single line with 3 calibration
values for all 4 sensors. The values are separated by colons and
are each 2 bytes long (encoded as 4 digit hexadecimal value).
First, 0kg values for all 4 sensors are written, followed by the
17kg values for all 4 sensors and last the 34kg values for all 4
sensors.
Calibration data is already applied by the kernel to all input
values but may be used by user-space to perform other
transformations.

* 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

* port and allow other extensions to be used simultaneously. This is all
