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

270 | * device's packet lengths, various maximum values, and tablet | |
271 | * resolution based on product ID's. | |
272 | * | |
273 | * For devices that contain 2 interfaces, wacom_features table is | |
274 | * inaccurate for the touch interface. Since the Interface Descriptor | |
275 | * for touch interfaces has pretty complete data, this function exists | |
276 | * to query tablet for this missing information instead of hard coding in | |
277 | * an additional table. | |
278 | * | |
279 | * A typical Interface Descriptor for a stylus will contain a | |
280 | * boot mouse application collection that is not of interest and this | |
281 | * function will ignore it. | |
282 | * | |
283 | * It also contains a digitizer application collection that also is not | |
284 | * of interest since any information it contains would be duplicate | |
285 | * of what is in wacom_features. Usually it defines a report of an array | |
286 | * of bytes that could be used as max length of the stylus packet returned. | |
287 | * If it happens to define a Digitizer-Stylus Physical Collection then | |
288 | * the X and Y logical values contain valid data but it is ignored. | |
289 | * | |
290 | * A typical Interface Descriptor for a touch interface will contain a | |
291 | * Digitizer-Finger Physical Collection which will define both logical | |
292 | * X/Y maximum as well as the physical size of tablet. Since touch | |
293 | * interfaces haven't supported pressure or distance, this is enough | |
294 | * information to override invalid values in the wacom_features table. | |
4134361a CB |
295 | * |
296 | * 3rd gen Bamboo Touch no longer define a Digitizer-Finger Pysical | |
297 | * Collection. Instead they define a Logical Collection with a single | |
