1What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/speed2Date: April 20103KernelVersion: 2.6.354Contact: linux-bluetooth@vger.kernel.org5Description:6 The /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/speed file7 controls reporting speed of Wacom bluetooth tablet. Reading8 from this file returns 1 if tablet reports in high speed mode9 or 0 otherwise. Writing to this file one of these values10 switches reporting speed.11 12What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/led13Date: August 201414Contact: linux-input@vger.kernel.org15Description: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 24HD20 (LEDs only). Therefore its presence implicitly signifies the21 presence of said LEDs and OLEDs on the tablet device.22 23What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status0_luminance24Date: August 201425Contact: linux-input@vger.kernel.org26Description:27 <obsoleted by the LED class API now exported by the driver>28 Writing to this file sets the status LED luminance (1..127)29 when the stylus does not touch the tablet surface, and no30 button is pressed on the stylus. This luminance level is31 normally lower than the level when a button is pressed.32 33What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status1_luminance34Date: August 201435Contact: linux-input@vger.kernel.org36Description:37 <obsoleted by the LED class API now exported by the driver>38 Writing to this file sets the status LED luminance (1..127)39 when the stylus touches the tablet surface, or any button is40 pressed on the stylus.41 42What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led0_select43Date: August 201444Contact: linux-input@vger.kernel.org45Description:46 <obsoleted by the LED class API now exported by the driver>47 Writing to this file sets which one of the four (for Intuos 448 and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq49 24HD) status LEDs is active (0..3). The other three LEDs on the50 same side are always inactive.51 52What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/status_led1_select53Date: August 201454Contact: linux-input@vger.kernel.org55Description:56 <obsoleted by the LED class API now exported by the driver>57 Writing to this file sets which one of the left four (for Cintiq 21UX258 and Cintiq 24HD) status LEDs is active (0..3). The other three LEDs on59 the left are always inactive.60 61What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/buttons_luminance62Date: August 201463Contact: linux-input@vger.kernel.org64Description:65 Writing to this file sets the overall luminance level (0..15)66 of all eight button OLED displays.67 68What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_led/button<n>_rawimg69Date: August 201470Contact: linux-input@vger.kernel.org71Description:72 When writing a 1024 byte raw image in Wacom Intuos 473 interleaving format to the file, the image shows up on Button N74 of the device. The image is a 64x32 pixel 4-bit gray image. The75 1024 byte binary is split up into 16x 64 byte chunks. Each 6476 byte chunk encodes the image data for two consecutive lines on77 the display. The low nibble of each byte contains the first78 line, and the high nibble contains the second line.79 When the Wacom Intuos 4 is connected over Bluetooth, the80 image has to contain 256 bytes (64x32 px 1 bit colour).81 The format is also scrambled, like in the USB mode, and it can82 be summarized by converting::83 84 76543210 into GECA6420.85 HGFEDCBA HFDB753186 87What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_remote/unpair_remote88Date: July 201589Contact: linux-input@vger.kernel.org90Description:91 Writing the character sequence '*' followed by a newline to92 this file will delete all of the current pairings on the93 device. Other character sequences are reserved. This file is94 write only.95 96What: /sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>/wacom_remote/<serial_number>/remote_mode97Date: July 201598Contact: linux-input@vger.kernel.org99Description:100 <obsoleted by the LED class API now exported by the driver>101 Reading from this file reports the mode status of the102 remote as indicated by the LED lights on the device. If no103 reports have been received from the paired device, reading104 from this file will report '-1'. The mode is read-only105 and cannot be set through the driver.106
