Due programming port

ard_newbie:
I guess the issue is with the USB VID of arduino.org inside Atmel16U2 software.

Maybe a Workaround:

Update your 16U2 software

And/or buy DUE clones :slight_smile:

Thank you, I will try to update the 16U2 software

What do you mean by buy DUE clones? We ordered the boards onto the official arduino web site
