Thank you . Tried . Before and after i got 03:00.0 network Controller Broadcom ….in sys-net settings underground devices always connected to this cube. I’ve used the commands proposed in your link with 93 instead of 02 to match my Device . No luck

I am out of luck also. Did you get this figured out? I also notice that the touchpad and keyboard on the MacBook is not working, but any external keyboard does, anyone know packages or how to obtain drivers 4 the kernel? thx
