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

122 | * device's packet lengths, various maximum values, and tablet | |
123 | * resolution based on product ID's. | |
124 | * | |
125 | * For devices that contain 2 interfaces, wacom_features table is | |
126 | * inaccurate for the touch interface. Since the Interface Descriptor | |
127 | * for touch interfaces has pretty complete data, this function exists | |
128 | * to query tablet for this missing information instead of hard coding in | |
129 | * an additional table. | |
130 | * | |
131 | * A typical Interface Descriptor for a stylus will contain a | |
132 | * boot mouse application collection that is not of interest and this | |
133 | * function will ignore it. | |
134 | * | |
135 | * It also contains a digitizer application collection that also is not | |
136 | * of interest since any information it contains would be duplicate | |
137 | * of what is in wacom_features. Usually it defines a report of an array | |
138 | * of bytes that could be used as max length of the stylus packet returned. | |
139 | * If it happens to define a Digitizer-Stylus Physical Collection then | |
140 | * the X and Y logical values contain valid data but it is ignored. | |
141 | * | |
142 | * A typical Interface Descriptor for a touch interface will contain a | |
143 | * Digitizer-Finger Physical Collection which will define both logical | |
144 | * X/Y maximum as well as the physical size of tablet. Since touch | |
145 | * interfaces haven't supported pressure or distance, this is enough | |
146 | * information to override invalid values in the wacom_features table. | |
