What:		/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/speed
Date:		April 2010
KernelVersion:	2.6.35
Contact:	linux-bluetooth@vger.kernel.org
Description:
		The /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/speed file
		controls reporting speed of Wacom bluetooth tablet. Reading
		from this file returns 1 if tablet reports in high speed mode
		or 0 otherwise. Writing to this file one of these values
		switches reporting speed.

What:		/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/led
Date:		August 2014
Contact:	linux-input@vger.kernel.org
Description:
		Attribute group for control of the status LEDs and the OLEDs.
		This attribute group is only available for Intuos 4 M, L,
		and XL (with LEDs and OLEDs), Intuos 4 WL, Intuos 5 (LEDs only),
		Intuos Pro (LEDs only) and Cintiq 21UX2 and Cintiq 24HD
		(LEDs only). Therefore its presence implicitly signifies the
		presence of said LEDs and OLEDs on the tablet device.

What:		/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status0_luminance
Date:		August 2014
Contact:	linux-input@vger.kernel.org
Description:
		<obsoleted by the LED class API now exported by the driver>
		Writing to this file sets the status LED luminance (1..127)
		when the stylus does not touch the tablet surface, and no
		button is pressed on the stylus. This luminance level is
		normally lower than the level when a button is pressed.

What:		/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status1_luminance
Date:		August 2014
Contact:	linux-input@vger.kernel.org
Description:
		<obsoleted by the LED class API now exported by the driver>
		Writing to this file sets the status LED luminance (1..127)
		when the stylus touches the tablet surface, or any button is
		pressed on the stylus.

What:		/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led0_select
Date:		August 2014
Contact:	linux-input@vger.kernel.org
Description:
		<obsoleted by the LED class API now exported by the driver>
		Writing to this file sets which one of the four (for Intuos 4
		and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq
		24HD) status LEDs is active (0..3). The other three LEDs on the
		same side are always inactive.

What:		/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led1_select
Date:		August 2014
Contact:	linux-input@vger.kernel.org
Description:
		<obsoleted by the LED class API now exported by the driver>
		Writing to this file sets which one of the left four (for Cintiq 21UX2
		and Cintiq 24HD) status LEDs is active (0..3). The other three LEDs on
		the left are always inactive.

What:		/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/buttons_luminance
Date:		August 2014
Contact:	linux-input@vger.kernel.org
Description:
		Writing to this file sets the overall luminance level (0..15)
		of all eight button OLED displays.
