+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.

+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.

+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.

+		24HD) status LEDs is active (0..3). The other three LEDs on the
+		same side are always inactive.

+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.
+		When the Wacom Intuos 4 is connected over Bluetooth, the
+		image has to contain 256 bytes (64x32 px 1 bit colour).
+		The format is also scrambled, like in the USB mode, and it can
+		be summarized by converting::
+
+					    76543210 into GECA6420.

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