^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) (RW) This attribute controls the amount of 'turn' permitted in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) Logitech G920 wheel. Reading from the file shows the current
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) range of the steering wheel. Writing a value within the min and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) max boundary sets the range of the wheel.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Presence of this file indicates that HID++ driver is capable of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) handling battery properties in the kernel. This way, upower can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) add a udev rule to decide whether or not it should use the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) internal unifying support or the generic kernel one.
