Sorry, haven't had an opportunity to try the suggestions yet. To clear things up, yes, I watched the Doom video. Yes, I used a USB 4 port hub, with a USB keyboard and the TP Link Dongle.
I want to be clear that I have never seen a version number listed on any of the listings. So, in order to "be safe", I ordered off the Amazon listing pointed to by the video that was identified as version 3.0. If Amazon is shiping V3.6 (and it appears they are), and version 3.6 is incompatible for whatever reason, someone really should I identify a seller who will reliably sell you V3, and remove the Amazon link from the video and/or elsewhere. I think it's also reasonable to assume that if TPLink is now producing V3.6, that they will cease to produce V3, and that V2 and V3 will become increasingly difficult to get, and it may be a good idea to start hunting for other compatible devices.
