Try this:
- Press the reset button on your MKR WAN 1300 twice quickly. You should now see the built-in LED continuously pulsing to indicate that the bootloader is running.
- Select the port of the MKR WAN 1300 from the Tools > Port menu. It will probably have a different port when the bootloader is running so don't assume you already had the correct port selected.
- Attempt an upload.
If things work out well, this will allow a successful upload. The hope is that after a successful upload using the "double-tap" technique, you will be able to upload normally. Please let me know what the results are.
Unfortunately that does not help either. In the Device Manager, although another COM port is active and I can change it, but it does not work. Same result. I had already tried before.
Something with the Arduino USB driver does not seem to work for me on this PC.
