Description:
		The /sys/class/hidraw/hidraw*/device/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.

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 5 (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.

Description:
		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.

Description:
		Writing to this file sets the status LED luminance (1..127)

Description:
		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.

Description:
		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.

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

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