I think ABS_MT_TOOL_TYPE is missing because mt_touch_input_mapping() has a = name check for the MT_CLS_WIN_8* classes which enables the MT_QUIRK_CONFIDENCE q= uirk which is later checked for to enable ABS_MT_TOOL_TYPE. And since the device= now has its own class it does not pass the check. Adding MT_QUIRK_CONFIDENCE explicitly should recover the missing ABS_MT_TOOL_TYPE. I'm attaching an updated patch, could you run the same tests you ran before? --=20 You may reply to this email to add a comment.
