Thanks Anssi! Your patch helped, device is passing pidff_find_reports(). Now stuck in pidff_find_fields(), with "unknown set_effect report layout". Looks like, device doesn't implement PID specs completely, as there is no gain and direction usages in set_effect report: >The minimal Effect parameter block must contain (Effect) Parameter Block Index, Effect Type, Duration, >Sample Period, Gain, Trigger Button, Trigger Repeat Interval, Axis Direction, and Type Specific Block >Handle values. But, looking into pidff_set_effect_report(), I think, it's possible to add two if's to check if these fields present. And need to make check for these fields optional somehow. These two usages are not fully utilized anyway, gain is always set to it's logical_maximum (actually it's used only in pidff_autocenter()) and direction is always set to 1. There is also some problem with pidff_find_special_fields() ("effect lists not found"), i'll add more debug messages and tell about that later. 2009/2/7 Anssi Hannula <anssi.hannula@xxxxxxxxx>: > Try the attached patch, which simply changes the collection type for > such collections. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
