Hi, > Out of curiosity, what camera are you using? Could you also share the > patch with the quirk? I have no idea what camera I am using ;) It's some dodgy no-name thing which doesn't even have "made in China" written on it and reports IDs belonging to a completely different kind of camera. But it sort of works, so what the heck. And I use the BW quirk with it because it otherwise asks for way too much. Squatting on others' IDs appears to be a fancy new cost reduction trick (not the first time I see it happen). I'm not really convinced that it would be a good idea to push quirks on such IDs upstream, but I figured the BW calculation fix could be useful. Regards, Michal
