| Description: |
| The /sys/class/hidraw/hidraw*/device/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) and Cintiq 21UX2 (LEDs only). |
| Therefore its presence implicitly signifies the presence of |
| said LEDs and OLEDs on the tablet device. |

| Description: |
| 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. |

| 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. |
