181 | * resolution based on product ID's. | |
182 | * | |
183 | * For devices that contain 2 interfaces, wacom_features table is | |
184 | * inaccurate for the touch interface. Since the Interface Descriptor | |

186 | * to query tablet for this missing information instead of hard coding in | |
187 | * an additional table. | |
188 | * | |
189 | * A typical Interface Descriptor for a stylus will contain a | |
190 | * boot mouse application collection that is not of interest and this | |
191 | * function will ignore it. | |
192 | * | |
193 | * It also contains a digitizer application collection that also is not | |
194 | * of interest since any information it contains would be duplicate | |
195 | * of what is in wacom_features. Usually it defines a report of an array | |
196 | * of bytes that could be used as max length of the stylus packet returned. | |
197 | * If it happens to define a Digitizer-Stylus Physical Collection then | |
198 | * the X and Y logical values contain valid data but it is ignored. | |
199 | * | |
200 | * A typical Interface Descriptor for a touch interface will contain a | |
201 | * Digitizer-Finger Physical Collection which will define both logical | |
202 | * X/Y maximum as well as the physical size of tablet. Since touch | |
203 | * interfaces haven't supported pressure or distance, this is enough | |
204 | * information to override invalid values in the wacom_features table. | |
