1189 | * - once a contact has been reported, it has to be reported in each | |
1190 | * subsequent report | |
1191 | * - the report rate when fingers are present has to be at least | |
1192 | * the refresh rate of the screen, 60 or 120 Hz | |
1193 | * | |
1194 | * I interprete this that the specification forces a report rate of | |
1195 | * at least 60 Hz for a touchscreen to be certified. | |
1196 | * Which means that if we do not get a report whithin 16 ms, either | |
1197 | * something wrong happens, either the touchscreen forgets to send | |
1198 | * a release. Taking a reasonable margin allows to remove issues | |
1199 | * with USB communication or the load of the machine. | |
1200 | * | |
1201 | * Given that Win 8 devices are forced to send a release, this will | |
