What is the advantage in having a device attach to both umsm(4) and umb(4)? What are you trying to accomplish? The EM7455 worked perfectly with umb(4) until your previous umsm(4) diff and now it only attaches as umsm(4). Are you wanting to send SMS messages or something like that with your devices? Bryan
