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.

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.

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.

24HD) status LEDs is active (0..3). The other three LEDs on the

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.

|
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.
