Thanks for the log, this will be very helpful, as I'm just figuring out there's something weird with the dd20 (select_source) message, the length is one byte too long (but it apparently used to work with the MF4270, MF4140 and MF4150), so I really need to review that with Dennis (did not discuss with him yet) before proposing a change.
Will keep you posted anyway.
