8Description:	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.

16Description:	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.

32Description:	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)
44			balanceboard: Wii Balance Board

50Description:	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.

65Description:	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.
