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
What: /sys/bus/hid/drivers/wiimote/<dev>/bboard_calib
Date: May 2013
KernelVersion: 3.11
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.
