Hi community, I am new to the Arduino community and I have some issues that I hope I can get some help. I have the opta, and have created some test function block diagram on the PLC IDE. It compiles fine without error. The issue is the download to the PLC that generates a fail with "No DFU capable USB device available"
First I can connect to the target with my USB without any problem. In my device manager I see port 10 and 12 and I believe opta use port 12 to connect to it. So any idea as to why I cannot download PLC code to the Opta. Below is the log
