+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

+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.
