1What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/speed 2Date: April 2010 3Kernel Version: 2.6.35 4Contact: linux-bluetooth@vger.kernel.org 5Description: 6 The /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/speed file 7 controls reporting speed of Wacom bluetooth tablet. Reading 8 from this file returns 1 if tablet reports in high speed mode 9 or 0 otherwise. Writing to this file one of these values 10 switches reporting speed. 11 12What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/led 13Date: August 2014 14Contact: linux-input@vger.kernel.org 15Description: 16 Attribute group for control of the status LEDs and the OLEDs. 17 This attribute group is only available for Intuos 4 M, L, 18 and XL (with LEDs and OLEDs), Intuos 4 WL, Intuos 5 (LEDs only), 19 Intuos Pro (LEDs only) and Cintiq 21UX2 and Cintiq 24HD 20 (LEDs only). Therefore its presence implicitly signifies the 21 presence of said LEDs and OLEDs on the tablet device. 22 23What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status0_luminance 24Date: August 2014 25Contact: linux-input@vger.kernel.org 26Description: 27 Writing to this file sets the status LED luminance (1..127) 28 when the stylus does not touch the tablet surface, and no 29 button is pressed on the stylus. This luminance level is 30 normally lower than the level when a button is pressed. 31 32What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status1_luminance 33Date: August 2014 34Contact: linux-input@vger.kernel.org 35Description: 36 Writing to this file sets the status LED luminance (1..127) 37 when the stylus touches the tablet surface, or any button is 38 pressed on the stylus. 39 40What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led0_select 41Date: August 2014 42Contact: linux-input@vger.kernel.org 43Description: 44 Writing to this file sets which one of the four (for Intuos 4 45 and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq 46 24HD) status LEDs is active (0..3). The other three LEDs on the 47 same side are always inactive. 48 49What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led1_select 50Date: August 2014 51Contact: linux-input@vger.kernel.org 52Description: 53 Writing to this file sets which one of the left four (for Cintiq 21UX2 54 and Cintiq 24HD) status LEDs is active (0..3). The other three LEDs on 55 the left are always inactive. 56 57What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/buttons_luminance 58Date: August 2014 59Contact: linux-input@vger.kernel.org 60Description: 61 Writing to this file sets the overall luminance level (0..15) 62 of all eight button OLED displays. 63 64What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/button<n>_rawimg 65Date: August 2014 66Contact: linux-input@vger.kernel.org 67Description: 68 When writing a 1024 byte raw image in Wacom Intuos 4 69 interleaving format to the file, the image shows up on Button N 70 of the device. The image is a 64x32 pixel 4-bit gray image. The 71 1024 byte binary is split up into 16x 64 byte chunks. Each 64 72 byte chunk encodes the image data for two consecutive lines on 73 the display. The low nibble of each byte contains the first 74 line, and the high nibble contains the second line. 75 When the Wacom Intuos 4 is connected over Bluetooth, the 76 image has to contain 256 bytes (64x32 px 1 bit colour). 77 The format is also scrambled, like in the USB mode, and it can 78 be summarized by converting 76543210 into GECA6420. 79 HGFEDCBA HFDB7531 80 81What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_remote/unpair_remote 82Date: July 2015 83Contact: linux-input@vger.kernel.org 84Description: 85 Writing the character sequence '*' followed by a newline to 86 this file will delete all of the current pairings on the 87 device. Other character sequences are reserved. This file is 88 write only. 89 90What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_remote/<serial_number>/remote_mode 91Date: July 2015 92Contact: linux-input@vger.kernel.org 93Description: 94 Reading from this file reports the mode status of the 95 remote as indicated by the LED lights on the device. If no 96 reports have been received from the paired device, reading 97 from this file will report '-1'. The mode is read-only 98 and cannot be set through the driver. 99
