The IDE no longer recognizes the programming port on my DUE (ttyACM0 not found). If I move the cable to the Native port, everything works. In the programming port, I do see power LEDs on, but it won’t upload and a sketch won’t print to the monitor. I assume one or more of the pins in the connector must have lost connection?? Any magic that might be applied?
I have tried another cable and tried hooking to a different computer … no luck.
(at least, it works with the Native port)
