OK, this is getting kind of confusing.  The Ubuntu forums that Daniel referenced earlier also report success with the MF4140.  However, the USB snoop logs from a MF4150 that Bob Dronsky sent me show a different packet format.  Is it possible that two different devices (MF4140 vs. MF4150) with two different protocols share the same USB VID/PID (04a9:26a3)?
