   5 Description:
   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.

  15 Description:
  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) and Cintiq 21UX2 and Cintiq 24HD
  19                 (LEDs only). Therefore its presence implicitly signifies the
  20                 presence of said LEDs and OLEDs on the tablet device.

  27                 when the stylus does not touch the tablet surface, and no
  28                 button is pressed on the stylus. This luminance level is
  29                 normally lower than the level when a button is pressed.

  66 Description:
  67                 When writing a 1024 byte raw image in Wacom Intuos 4
  68                 interleaving format to the file, the image shows up on Button N
  69                 of the device. The image is a 64x32 pixel 4-bit gray image. The
  70                 1024 byte binary is split up into 16x 64 byte chunks. Each 64
  71                 byte chunk encodes the image data for two consecutive lines on
  72                 the display. The low nibble of each byte contains the first
  73                 line, and the high nibble contains the second line.
