Thanks! This is what I eventually got to. That said, I'm leaning towards putting the USB stick in a Pi or something like that, which is attached to and powered by the router!

Just want to have the one device and I think that's maybe the simplest way to get it without trying to run stuff on the router.

Basically, it is a hub, but it's more of an attachment to the router than anything else.
