And it can be accompanied by the *explicit* feedback endpoint. I have patches that implement autodetection of implicit feedback, but I need to clean them up and be careful not to break Scarlett 18i8/18i20 3rd Gen (these devices have 3 altsettings per interface and probably require some additional sample rates filtering, so that each sample rate uniquely match one single altsetting).
Alexander, thanks for the clarification. If I understand correctly the existing single-interface condition is incorrect and no implicit-feedback device can work without a quirk now.
Thanks for your WIP patches, very much appreciated. Best regards, Pavel.
