5Description:
6		The /sys/class/hidraw/hidraw*/device/speed file controls
7		reporting speed of Wacom bluetooth tablet. Reading from
8		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.

23Description:
24		Attribute group for control of the status LEDs and the OLEDs.
25		This attribute group is only available for Intuos 4 M, L,
26		and XL (with LEDs and OLEDs), Intuos 5 (LEDs only), and Cintiq
27		21UX2 and Cintiq 24HD (LEDs only). Therefore its presence
28		implicitly signifies the presence of said LEDs and OLEDs on the
29		tablet device.

34Description:
35		Writing to this file sets the status LED luminance (1..127)
36		when the stylus does not touch the tablet surface, and no
37		button is pressed on the stylus. This luminance level is
38		normally lower than the level when a button is pressed.

75Description:
76		When writing a 1024 byte raw image in Wacom Intuos 4
77		interleaving format to the file, the image shows up on Button N
78		of the device. The image is a 64x32 pixel 4-bit gray image. The
79		1024 byte binary is split up into 16x 64 byte chunks. Each 64
80		byte chunk encodes the image data for two consecutive lines on
81		the display. The low nibble of each byte contains the first
82		line, and the high nibble contains the second line.
