What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/speed
Date: April 2010
Kernel Version: 2.6.35
Contact: linux-bluetooth@vger.kernel.org
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.
What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/led
Date: August 2014
Contact: linux-input@vger.kernel.org
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.
What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status0_luminance
Date: August 2014
Contact: linux-input@vger.kernel.org
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.
What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status1_luminance
Date: August 2014
Contact: linux-input@vger.kernel.org
Description:
Writing to this file sets the status LED luminance (1..127)
when the stylus touches the tablet surface, or any button is
pressed on the stylus.
What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led0_select
Date: August 2014
Contact: linux-input@vger.kernel.org
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.

Date: August 2014
Contact: linux-input@vger.kernel.org
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.
What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/buttons_luminance
Date: August 2014
Contact: linux-input@vger.kernel.org
Description:
Writing to this file sets the overall luminance level (0..15)
of all eight button OLED displays.
What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/button<n>_rawimg
Date: August 2014
Contact: linux-input@vger.kernel.org
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.

Date: July 2015
Contact: linux-input@vger.kernel.org
Description:
Writing the character sequence '*' followed by a newline to
this file will delete all of the current pairings on the
device. Other character sequences are reserved. This file is
write only.
What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_remote/<serial_number>/remote_mode
Date: July 2015
Contact: linux-input@vger.kernel.org
Description:
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.
