+Description:
+ (RW) This attribute controls the amount of 'turn' permitted in
+ Logitech G920 wheel. Reading from the file shows the current

+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.
