It's not the fact of having an actual "file" telling you what to do and install, it is just how linux is "written," so to speak. If you would have posted on these forums about how to get your network devices to work, we would have steered you in a direction on how to get them to work, just like the way you did, only with commands and different ways to gather the resources needed.
But besides that point, I'm glad that you got it figured out on your own! You almost sound like a natural
Cheers, and all the best,
