5Description:
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.

15Description:
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.

26Description:
27		<obsoleted by the LED class API now exported by the driver>
28		Writing to this file sets the status LED luminance (1..127)
29		when the stylus does not touch the tablet surface, and no
30		button is pressed on the stylus. This luminance level is
31		normally lower than the level when a button is pressed.

47		Writing to this file sets which one of the four (for Intuos 4
48		and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq
49		24HD) status LEDs is active (0..3). The other three LEDs on the
50		same side are always inactive.

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

88Description:

90		this file will delete all of the current pairings on the
91		device. Other character sequences are reserved. This file is

97Description:
98		<obsoleted by the LED class API now exported by the driver>
99		Reading from this file reports the mode status of the
100		remote as indicated by the LED lights on the device. If no
101		reports have been received from the paired device, reading
102		from this file will report '-1'. The mode is read-only
103		and cannot be set through the driver.
