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. 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. 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. HGFEDCBA HFDB7531 What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_remote/unpair_remote 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.
