204 | * device's packet lengths, various maximum values, and tablet | |
205 | * resolution based on product ID's. | |
206 | * | |
207 | * For devices that contain 2 interfaces, wacom_features table is | |
208 | * inaccurate for the touch interface. Since the Interface Descriptor | |
209 | * for touch interfaces has pretty complete data, this function exists | |
210 | * to query tablet for this missing information instead of hard coding in | |
211 | * an additional table. | |
212 | * | |
213 | * A typical Interface Descriptor for a stylus will contain a | |
214 | * boot mouse application collection that is not of interest and this | |
215 | * function will ignore it. | |
216 | * | |
217 | * It also contains a digitizer application collection that also is not | |
218 | * of interest since any information it contains would be duplicate | |
219 | * of what is in wacom_features. Usually it defines a report of an array | |
220 | * of bytes that could be used as max length of the stylus packet returned. | |
221 | * If it happens to define a Digitizer-Stylus Physical Collection then | |
222 | * the X and Y logical values contain valid data but it is ignored. | |
223 | * | |
224 | * A typical Interface Descriptor for a touch interface will contain a | |
225 | * Digitizer-Finger Physical Collection which will define both logical | |
226 | * X/Y maximum as well as the physical size of tablet. Since touch | |
227 | * interfaces haven't supported pressure or distance, this is enough | |
228 | * information to override invalid values in the wacom_features table. | |
