    Just got this really amazing device, got it up and running on Linux and have been able to change modes and all that. Unfortunately, can’t get it to work on OSX at all. Running Monterrey — OSX 12.3 on an Intel Mac (but I’ve also tested it running the same version on an ARM Mac with similar results). There is no /dev/cu.usbmodem* device or /dev/ttyACM* device created when the device is plugged in as there would be normally if the device were enumerating as a USB-CDC serial port or something of the like.

    I’ve tried the device plugged directly USB-C to USB-C, I’ve also tried it plugged USB-C to USB-A hub – USB-C on the Mac, same results. running a VM with Linux on the Mac and assigning the device to the VM does work, so there’s not a hardware issue that I can figure out.

    These seem to be relevant log entries, though I’m really not sure what they mean and don’t find any relevant discussion on similar log entries online anywhere:
