I will try to answer this one at a time.
The project is to gather information from the CAN BUS of a 2011 car. I need to find what gear the transmission is in. I bought the Marduino Zero CANBUS board to accomplish this. In my surch for a program I did find arduino code to do this. Now I am trying to program the board with this code. The instructions with the code tells you to use the native USB port.
ZX80 has a link that further explains how to program the board.
Query this "Marduino Zero CANBUS board native USB port, programming port" and it describes the programming port and the native USB port. I am trying to determine where the native USB port is. I now thing it is #2 on the picture above.
