Instead of just failing it will try to continue probing. Now that we are at it, add a quirk to fix an Avermedia device affected by this error. Why keep using the quirk? Because I think it is more correct to handle them that way and the quirk system can give us an idea of what vendors are more respectful with the spec. Thanks!
