212 | * resolution based on product ID's. | |

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

224 | * It also contains a digitizer application collection that also is not | |
225 | * of interest since any information it contains would be duplicate | |
226 | * of what is in wacom_features. Usually it defines a report of an array | |
227 | * of bytes that could be used as max length of the stylus packet returned. | |

231 | * A typical Interface Descriptor for a touch interface will contain a | |
232 | * Digitizer-Finger Physical Collection which will define both logical | |
233 | * X/Y maximum as well as the physical size of tablet. Since touch | |
234 | * interfaces haven't supported pressure or distance, this is enough | |
235 | * information to override invalid values in the wacom_features table. | |
