My AudioBox is a few years old and I am running Catalina on my mac. When I plug in the box, it lights up like its receiving power and it all seems like it's going to work. When I open the garage band, it cannot detect it. In the preferences of garage band, it is nowhere to be seen. In the system preferences under audio, it isn't a listed input and finally, in the system report, it is not showing as connected to the computer. Basically, my takeaway is that the system isn't even acknowledging its existence.
I updated to the most recent universal control and even it, does not recognize it. My computer has 2 USB ports and it hasn't worked on either. Further, I've plugged in other devices into the same USB ports and they all work fine. Any thoughts?
