+What:          /sys/bus/hid/drivers/logitech-hidpp-device/<dev>/range

+KernelVersion: 4.6
+               (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.
+Date:          Apr, 2017
+KernelVersion: 4.12
+               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.
