Mac mini (2018) Macmini8,1 Linux usb-c will not recognize certain usb device types
Solution 1:
What is not working is hotplug of any device 5+ Gb/s on Apple computers with Intel cpu, 2016+
At boot time, devices are recognized by efi firmware. After that, any unplugged device is gone until again plugged in during boot
