Well, the problem seems to be that there's no dedicated physical USB 3.0 port on my
machine, the physical
port act as the one or the other depending on what you connect.
All physical ports have the SuperSpeed symbol, but none of them automatically connects to
the
(internal) USB 3.0 root hub if I connect a USB 2.0 device, so I assume there's some
logic that
detects whether the connected device is 2.0 or 3.0 and connects it accordingly. Like, when
I connect
a USB 3.0 storage device, lsusb shows it as connected to the 3.0 bus.
So I my guess would be, if I use a dedicated (external) USB 3.0 hub, it would be detected
as a 3.0 device
and routed to the (internal) 3.0 bus, and thus the devices connected to the external hub
would be as well.
But, of course, that's just speculation. I might just get a 3.0 hub and try.

USB 3 is backward compatible. Occasionally I connect an USB 2 Scarlett
18i20 2nd gen to a GA-B85M-D3H mobo's USB 3 slot of an Arch Linux
machine. This works without issues and allows lower latency, than is
possible with a PCIe slot assembled RME HDSPe AIO on the same machine.
Even if the USB 3 port shouldn't be the best for an audio device on
your machine, it at least should sort of work, perhaps causing xruns.
That it doesn't work at all, might be a pointer to an issue of your
computer.
