What's interesting to me is the part of this design that isn't junk: the single wired-through-to-the-host USB3 port. Why don't more hubs do this? I'd love to have access to a cheap port expander that lets me plug my junk in without losing access to the high speed port on the laptop. But no one sells that. You get a full USB3 hub, which is mostly wasteful for an input dongle or UART adapter, or a USB2 one that forces you to juggle stuff around when you need to plug in a thumb drive.
