Yep, I know that the hub is not terribly expensive (more if I have someone else install it, but still not bad). I’ve just elected not to do it.
It’s not that I have “bad info” regarding 3.3 vs 3.4. It’s because I tried it (see Need help downgrading: 3.4.x to 3.0.x). I received the “USB hubs are not recognized” error when I first tried to upgrade to 3.4.x. I tried the lowest available 3.4 version and still received the error, so went down to 3.3.19052 - no more error. I’ll probably install the upgraded hub at some point but don’t want to right now.
