I have a Mac mini M1. I'm trying to develop communications between 2 AdaFruit Feather M0 radio boards.
I need to be able to use both concurrently., but Arduino (and the Mac USB system) is only seeing the one I have plugged into the Usb-C/Thunderbolt port. The second USB-C port is needed for the display, so I have the other Feather connected via one of the Usb-A ports.
I'm desperately looking for help.
