0008 Description: Make it possible to set/get current led state. Reading from it
0009 returns 0 if led is off and 1 if it is on. Writing 0 to it
0010 disables the led, writing 1 enables it.

0016 Description: This file contains the currently connected and initialized
0017 extensions. It can be one of: none, motionp, nunchuck, classic,
0018 motionp+nunchuck, motionp+classic
0019 motionp is the official Nintendo Motion+ extension, nunchuck is
0020 the official Nintendo Nunchuck extension and classic is the
0021 Nintendo Classic Controller extension. The motionp extension can
0022 be combined with the other two.
0023
0024 Starting with kernel-version 3.11 Motion Plus hotplugging is
0025 supported and if detected, it's no longer reported as static
0026 extension. You will get uevent notifications for the motion-plus
0027 device then.

0033 Description: While a device is initialized by the wiimote driver, we perform
0034 a device detection and signal a "change" uevent after it is
0035 done. This file shows the detected device type. "pending" means
0036 that the detection is still ongoing, "unknown" means, that the
0037 device couldn't be detected or loaded. "generic" means, that the
0038 device couldn't be detected but supports basic Wii Remote
0039 features and can be used.
0040 Other strings for each device-type are available and may be
0041 added if new device-specific detections are added.
0042 Currently supported are:

0046 gen20: Second Wii Remote Plus generation

0055 Description: This attribute is only provided if the device was detected as a
0056 balance board. It provides a single line with 3 calibration
0057 values for all 4 sensors. The values are separated by colons and
0058 are each 2 bytes long (encoded as 4 digit hexadecimal value).
0059 First, 0kg values for all 4 sensors are written, followed by the
0060 17kg values for all 4 sensors and last the 34kg values for all 4
0061 sensors.
0062
0063 Calibration data is already applied by the kernel to all input
0064 values but may be used by user-space to perform other
0065 transformations.

0071 Description: This attribute is only provided if the device was detected as a
0072 pro-controller. It provides a single line with 4 calibration
0073 values for all 4 analog sticks. Format is: "x1:y1 x2:y2". Data
0074 is prefixed with a +/-. Each value is a signed 16bit number.
0075 Data is encoded as decimal numbers and specifies the offsets of
0076 the analog sticks of the pro-controller.
0077
0078 Calibration data is already applied by the kernel to all input
0079 values but may be used by user-space to perform other
0080 transformations.
0081
0082 Calibration data is detected by the kernel during device setup.
0083 You can write "scan\n" into this file to re-trigger calibration.
0084 You can also write data directly in the form "x1:y1 x2:y2" to
0085 set the calibration values manually.
