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

  16 Description:    This file contains the currently connected and initialized
  17                 extensions. It can be one of: none, motionp, nunchuck, classic,
  18                 motionp+nunchuck, motionp+classic
  19                 motionp is the official Nintendo Motion+ extension, nunchuck is
  20                 the official Nintendo Nunchuck extension and classic is the
  21                 Nintendo Classic Controller extension. The motionp extension can
  22                 be combined with the other two.
  23                 Starting with kernel-version 3.11 Motion Plus hotplugging is
  24                 supported and if detected, it's no longer reported as static
  25                 extension. You will get uevent notifications for the motion-plus
  26                 device then.

  32 Description:    While a device is initialized by the wiimote driver, we perform
  33                 a device detection and signal a "change" uevent after it is
  34                 done. This file shows the detected device type. "pending" means
  35                 that the detection is still ongoing, "unknown" means, that the
  36                 device couldn't be detected or loaded. "generic" means, that the
  37                 device couldn't be detected but supports basic Wii Remote
  38                 features and can be used.
  39                 Other strings for each device-type are available and may be
  40                 added if new device-specific detections are added.
  41                 Currently supported are:
  42                         gen10: First Wii Remote generation
  43                         gen20: Second Wii Remote Plus generation (builtin MP)

  50 Description:    This attribute is only provided if the device was detected as a
  51                 balance board. It provides a single line with 3 calibration
  52                 values for all 4 sensors. The values are separated by colons and
  53                 are each 2 bytes long (encoded as 4 digit hexadecimal value).
  54                 First, 0kg values for all 4 sensors are written, followed by the
  55                 17kg values for all 4 sensors and last the 34kg values for all 4
  56                 sensors.
  57                 Calibration data is already applied by the kernel to all input
  58                 values but may be used by user-space to perform other
  59                 transformations.

  65 Description:    This attribute is only provided if the device was detected as a
  66                 pro-controller. It provides a single line with 4 calibration
  67                 values for all 4 analog sticks. Format is: "x1:y1 x2:y2". Data
  68                 is prefixed with a +/-. Each value is a signed 16bit number.
  69                 Data is encoded as decimal numbers and specifies the offsets of
  70                 the analog sticks of the pro-controller.
  71                 Calibration data is already applied by the kernel to all input
  72                 values but may be used by user-space to perform other
  73                 transformations.
  74                 Calibration data is detected by the kernel during device setup.
  75                 You can write "scan\n" into this file to re-trigger calibration.
  76                 You can also write data directly in the form "x1:y1 x2:y2" to
  77                 set the calibration values manually.
