What: /sys/bus/hid/drivers/logitech-hidpp-device/<dev>/range
Date: Jan, 2016
KernelVersion: 4.6
Contact: linux-input@vger.kernel.org
Description:
(RW) This attribute controls the amount of 'turn' permitted in
Logitech G920 wheel. Reading from the file shows the current
range of the steering wheel. Writing a value within the min and
max boundary sets the range of the wheel.
What: /sys/bus/hid/drivers/logitech-hidpp-device/<dev>/builtin_power_supply
Date: Apr, 2017
KernelVersion: 4.12
Contact: linux-input@vger.kernel.org
Description:
Presence of this file indicates that HID++ driver is capable of
handling battery properties in the kernel. This way, upower can
add a udev rule to decide whether or not it should use the
internal unifying support or the generic kernel one.

What: /sys/bus/hid/drivers/ntrig/<dev>/activate_slack

KernelVersion: 2.6.35

Description:
(RW) Number of contact frames ignored before acknowledging the
start of activity (activating touch).
What: /sys/bus/hid/drivers/ntrig/<dev>/decativate_slack
Date: May, 2010
KernelVersion: 2.6.35
Contact: linux-input@vger.kernel.org
Description:
(RW) Number of empty (no contact) frames ignored before
acknowledging the end of activity (deactivating touch).
When the last finger is removed from the device, it sends a
number of empty frames. By holding off on deactivation for a few
frames false erroneous disconnects can be tolerated, where the
sensor may mistakenly not detect a finger that is still present.

activation and activity.
