Description: This file contains the currently connected and initialized
extensions. It can be one of: none, motionp, nunchuck, classic,
motionp+nunchuck, motionp+classic
@ -20,3 +20,40 @@ Description: This file contains the currently connected and initialized
the official Nintendo Nunchuck extension and classic is the
Nintendo Classic Controller extension. The motionp extension can
be combined with the other two.
Starting with kernel-version 3.11 Motion Plus hotplugging is
supported and if detected, it's no longer reported as static
extension. You will get uevent notifications for the motion-plus
device then.
What: /sys/bus/hid/drivers/wiimote/<dev>/devtype
Date: May 2013
KernelVersion: 3.11
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.

---help---
Support for extension controllers of the Nintendo Wii Remote. Say yes
here if you want to use the Nintendo Motion+, Nunchuck or Classic
extension controllers with your Wii Remote.
Support for all official Nintendo extensions is available, however, 3rd
party extensions might not be supported. Please report these devices to:
http://github.com/dvdhrm/xwiimote/issues
Other Nintendo Wii U peripherals that are IEEE 802.11 based (including
the Wii U Gamepad) might be supported in the future. But currently
support is limited to Bluetooth based devices.
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called hid-wiimote.
