+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

+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.

+ (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.
