- What: /sys/class/hidraw/hidraw*/device/speed
- Date: April 2010
- Kernel Version: 2.6.35
- Contact: linux-bluetooth@vger.kernel.org
- 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.

- Date: August 2011
- 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) and Cintiq 21UX2 (LEDs only).
- Therefore its presence implicitly signifies the presence of
- said LEDs and OLEDs on the tablet device.

- Date: August 2011
- 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.

- 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/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status_led0_select
- Date: August 2011
- Contact: linux-input@vger.kernel.org
- Description:
- Writing to this file sets which one of the four (for Intuos 4)
- or of the right four (for Cintiq 21UX2) status LEDs is active (0..3).
- The other three LEDs on the same side are always inactive.
- What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status_led1_select
- Date: September 2011
- Contact: linux-input@vger.kernel.org
- Description:
- Writing to this file sets which one of the left four (for Cintiq 21UX2)
- status LEDs is active (0..3). The other three LEDs on the left are always
- inactive.

- Date: August 2011
- 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 2011
- 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.
