- 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.

- 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.

- 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.
- What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led1_select
- 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.

- 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.
