 Description:	This file contains the currently connected and initialized
 		extensions. It can be one of: none, motionp, nunchuck, classic,
 		motionp+nunchuck, motionp+classic
 		motionp is the official Nintendo Motion+ extension, nunchuck is
 		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.

+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

+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.
