The need for WRONG_SCO_MTU detail can be easily determined. Check the output of hciconfig without this quirk. If the SCO MTU essentially shows 0 values, then you need it. But then again, you are just randomly adding quirks without understanding what they are for. This makes me worry a lot. Are you actually running a recent 3.x kernel or are you just using an outdated kernel? Regards Marcel
