@fossette Thank you. Should have replied earlier, but I have been continuing my research.
I have also been offered the Raspberry PI Zero, but it seems awfully limited, with only one USB port. If I use that as the pseudo-device, then I have no other communication with the board, or can I use their USB + Ethernet adapter ( hub ), as well as making one of the ports on that adapter into the "device?" I wouldn't think so.
I think that the article that you referred to will be my best bet, along with a suitable "computer," whether it is a Raspberry PI ( not Zero ) or something else. I wouldn't think that I could use a pre-built computer ( laptop ), because their hardware and drivers ( even Linux ) are pre-determined.
