217 | * For devices that contain 2 interfaces, wacom_features table is | |

230 | * of bytes that could be used as max length of the stylus packet returned. | |

235 | * Digitizer-Finger Physical Collection which will define both logical | |
236 | * X/Y maximum as well as the physical size of tablet. Since touch | |
