In my initial trials and tribulations with this thing, the driver was
the first thing I checked. No, got the correct one. Just had to
install the non-free Realtek firmware package which I did before even
plugging it in.
But as it turned out, my "problem" was me trying to get it to come up
at boot which the system and software and device weren't designed to
do. Unfortunately, I didn't initially realize that.
Thanks for your reply.
