CubeProgrammer 2.22.0 under MacOS 26.4.1 is not able to connect to my NUCLEO-G431, with the log window showing:
ST-LINK error (DEV_CONNECT_ERR)
Strange thing is this only happens when I have a direct cable connection between the USB-C port on the Mac and the ST-LINK V3 USB on the board - it works as expected if I connect via a USB-C hub.
VS Code is also not able to connect to the board to run a debug session without the hub, so I suspect this is an ST-LINK USB driver issue on the Mac.
