| 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. | |

| 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. | |

| Writing to this file sets which one of the four (for Intuos 4 | |
| and Intuos 5) or of the right four (for Cintiq 21UX2 and Cintiq | |
| 24HD) status LEDs is active (0..3). The other three LEDs on the | |
| same side are always inactive. | |

| 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. | |
