I haven't tried any hubs, but my problem was using a 2.5 Gbps USB Ethernet controller off of one of the Fresco Logic USB ports (the front 5 Gbps ones or the rear right-hand 3 USB-A ports), after a few hours it would drop. I thought the cheap USB adapter was bad, replaced it, same thing.

I found this blog post, switched to one of the ASMedia ports (the rear 10 Gbps USB-C port or the most left-hand USB-A port) and both of the Ethernet controllers are rock-solid now.

I now have it in the Thunderbolt port which ekes out another 100 Mbps or so compared to the ASMedia USB ports.

The blog post is probably a bit sensationalistic but I still can't recommend the dock to anyone when half the ports on it are flakey, especially at that price.

Sounds like I should plug the subset of the ports that are on that Fresco Logic controller so that I don't unwittingly use them at some point in the distant future.

This is understandable.

However, I'm pleased with my purchase and I'm only using the built-in Ethernet port, the built-in DisplayPort port, and a couple of USB ports. If it lasts me five years, I will have paid ~60 USD per year, which I think is a bargain when you compare it to fighting with something that's flaky no matter what you do, or just fails after a year or two... requiring you to go on the hunt for a new "dock".

Honestly, I think it's pretty damn stupid to have so many USB ports on the thing to begin with. Decent USB hubs are inexpensive; remove all but one or two of the USB ports and use now-spare bandwidth to put additional DisplayPort ports on the thing!
