| 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. |

| 16 | Attribute group for control of the status LEDs and the OLED |
| 17 | displays found on the Wacom Intuos 4 M, L, and XL tablets. This |
| 18 | attribute group is not available for other Wacom tablets. |
| 19 | Therefore its presence implicitly signifies the presence of |
| 20 | said LEDs and OLED displays on the tablet device. |

| 42 | Writing to this file sets which one of the four status LEDs is |
| 43 | active (0..3). The other three LEDs are always inactive. By |
| 44 | means of specifying "-1" it is possible to set all status LEDs |
| 45 | to inactive. |

| 57 | Description: |
| 58 | When writing a 1024 byte raw image in Wacom Intuos 4 |
| 59 | interleaving format to the file, the image shows up on Button N |
| 60 | of the device. The image is a 64x32 pixel 4-bit gray image. The |
| 61 | 1024 byte binary is split up into 16x 64 byte chunks. Each 64 |
| 62 | byte chunk encodes the image data for two consecutive lines on |
| 63 | the display. The low nibble of each byte contains the first |
| 64 | line, and the high nibble contains the second line. |
