1What: /sys/class/hidraw/hidraw*/device/speed 2Date: April 2010 3Kernel Version: 2.6.35 4Contact: linux-bluetooth@vger.kernel.org 5Description: 6 The /sys/class/hidraw/hidraw*/device/speed file controls 7 reporting speed of Wacom bluetooth tablet. Reading from 8 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/class/leds/0005\:056A\:00BD.0001\:selector\:*/ 13Date: May 2012 14Kernel Version: 3.5 15Contact: linux-bluetooth@vger.kernel.org 16Description: 17 LED selector for Intuos4 WL. There are 4 leds, but only one LED 18 can be lit at a time. Max brightness is 127. 19 20What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/led 21Date: August 2011 22Contact: linux-input@vger.kernel.org 23Description: 24 Attribute group for control of the status LEDs and the OLEDs. 25 This attribute group is only available for Intuos 4 M, L, 26 and XL (with LEDs and OLEDs), Intuos 5 (LEDs only), and Cintiq 27 21UX2 and Cintiq 24HD (LEDs only). Therefore its presence 28 implicitly signifies the presence of said LEDs and OLEDs on the 29 tablet device. 30 31What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status0_luminance 32Date: August 2011 33Contact: linux-input@vger.kernel.org 34Description: 35 Writing to this file sets the status LED luminance (1..127) 36 when the stylus does not touch the tablet surface, and no 37 button is pressed on the stylus. This luminance level is 38 normally lower than the level when a button is pressed. 39 40What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status1_luminance 41Date: August 2011 42Contact: linux-input@vger.kernel.org 43Description: 44 Writing to this file sets the status LED luminance (1..127) 45 when the stylus touches the tablet surface, or any button is 46 pressed on the stylus. 47 48What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status_led0_select 49Date: August 2011 50Contact: linux-input@vger.kernel.org 51Description: 52 Writing to this file sets which one of the four (for Intuos 4 53 and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq 54 24HD) status LEDs is active (0..3). The other three LEDs on the 55 same side are always inactive. 56 57What: /sys/bus/usb/devices/<busnum>-<devnum>:<cfg>.<intf>/wacom_led/status_led1_select 58Date: September 2011 59Contact: linux-input@vger.kernel.org 60Description: 61 Writing to this file sets which one of the left four (for Cintiq 21UX2 62 and Cintiq 24HD) status LEDs is active (0..3).

The image is a 64x32 pixel 4-bit gray image. The 79 1024 byte binary is split up into 16x 64 byte chunks. Each 64 80 byte chunk encodes the image data for two consecutive lines on 81 the display. The low nibble of each byte contains the first 82 line, and the high nibble contains the second line. 83
