@Dojima 's process worked for me on BigSur. I did not need to install any extra drivers.
I was able to get it to connect two ways. I plugged in the C-to-A adapter in, waited a few seconds. Turned the snapmaker on, waited till it booted. Then plugged the snapmaker into the USB-A adapter.
After that worked, I plugged the snapmaker into my USB-A hub, which also worked.
I’m going to continue playing with it, but this is the first time I’ve gotten Luban to talk to the snapmaker.
