146 | * Interface Descriptor of wacom devices can be incomplete and | |

148 | * device's packet lengths, various maximum values, and tablet | |
149 | * resolution based on product ID's. | |
150 | * | |
151 | * For devices that contain 2 interfaces, wacom_features table is | |
152 | * inaccurate for the touch interface. Since the Interface Descriptor | |
153 | * for touch interfaces has pretty complete data, this function exists | |
154 | * to query tablet for this missing information instead of hard coding in | |
155 | * an additional table. | |
156 | * | |
157 | * A typical Interface Descriptor for a stylus will contain a | |
158 | * boot mouse application collection that is not of interest and this | |
159 | * function will ignore it. | |
160 | * | |
161 | * It also contains a digitizer application collection that also is not | |
162 | * of interest since any information it contains would be duplicate | |
163 | * of what is in wacom_features. Usually it defines a report of an array | |
164 | * of bytes that could be used as max length of the stylus packet returned. | |
165 | * If it happens to define a Digitizer-Stylus Physical Collection then | |
166 | * the X and Y logical values contain valid data but it is ignored. | |
167 | * | |
168 | * A typical Interface Descriptor for a touch interface will contain a | |
169 | * Digitizer-Finger Physical Collection which will define both logical | |
170 | * X/Y maximum as well as the physical size of tablet. Since touch | |
171 | * interfaces haven't supported pressure or distance, this is enough | |
172 | * information to override invalid values in the wacom_features table. | |
