Recently I am having issues with the Arduino IDE resulting in seeing the very same COM port number often twice and to a lesser degree up to four times. This despite the Device Manager only having one Arduino Zero COM port listed.
When it happens the uploading fails to finish but sometimes the code is still uploaded. Sometimes I have to unplug and restart the PC before I can proceed. I have tried to reburn the bootloader but in vain.
Double clicking the reset button doesn’t help either - as it does when the upload COM port isn’t found. But probably this is no surprise because the COM port is seen multiple times.
Why is this?
What can I do to stop this from happening?
It might be that this is something related to 1.8.9 because I can’t remember if it has happened before.
