When I plug my Pynq Z2 board into my M1 mac, the /dev/tty.usbserial… doesn’t get created, so I can’t communicate with the board with screen or minicom. I can talk to it with this program:  
[https://www.decisivetactics.com/products/serial/](https://www.decisivetactics.com/products/serial/)  
but I’d like to avoid paying $39.00 when the trial runs out if I can.

It also won’t connect to my Win11 VM. It sees two USB Serial devices, but doesn’t create a COM port, but then the M1 version of Win11 is kind of a beta release at the moment.

So far, the only way I’ve succeeded in talking to it for free is using minicom on my Ubuntu VM, which is a little kludgy.

Any advice would be appreciated.
