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

15	Description:
16			Attribute group for control of the status LEDs and the OLEDs.
17			This attribute group is only available for Intuos 4 M, L,
18			and XL (with LEDs and OLEDs), Intuos 4 WL, Intuos 5 (LEDs only),
19			Intuos Pro (LEDs only) and Cintiq 21UX2 and Cintiq 24HD
20			(LEDs only). Therefore its presence implicitly signifies the
21			presence of said LEDs and OLEDs on the tablet device.

24	Date:		August 2014
25	Contact:	linux-input@vger.kernel.org
26	Description:
27			Writing to this file sets the status LED luminance (1..127)
28			when the stylus does not touch the tablet surface, and no
29			button is pressed on the stylus. This luminance level is
30			normally lower than the level when a button is pressed.

35	Description:
36			Writing to this file sets the status LED luminance (1..127)
37			when the stylus touches the tablet surface, or any button is
38			pressed on the stylus.

43	Description:
44			Writing to this file sets which one of the four (for Intuos 4
45			and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq
46			24HD) status LEDs is active (0..3). The other three LEDs on the
47			same side are always inactive.

52	Description:
53			Writing to this file sets which one of the left four (for Cintiq 21UX2
54			and Cintiq 24HD) status LEDs is active (0..3). The other three LEDs on
55			the left are always inactive.

60	Description:
61			Writing to this file sets the overall luminance level (0..15)
62			of all eight button OLED displays.

67	Description:
68			When writing a 1024 byte raw image in Wacom Intuos 4
69			interleaving format to the file, the image shows up on Button N
70			of the device. The image is a 64x32 pixel 4-bit gray image. The
71			1024 byte binary is split up into 16x 64 byte chunks. Each 64
72			byte chunk encodes the image data for two consecutive lines on
73			the display. The low nibble of each byte contains the first
74			line, and the high nibble contains the second line.
75			When the Wacom Intuos 4 is connected over Bluetooth, the
76			image has to contain 256 bytes (64x32 px 1 bit colour).
77			The format is also scrambled, like in the USB mode, and it can
78			be summarized by converting 76543210 into GECA6420.
