This Realtek RTS5401 USB 3.0 hub is combined in a case with three USB 3.0

Connected to a USB 2.0 port, it shows this:

I have not tried it on a USB 3.0 port yet.
It would not really bother me if only the Ethernet worked, but surely it is
connected to the hub, so will be all or nothing. Any suggestions?
On a USB 3.0 port on a -CURRENT system (r297315), the hub is recognized

Are USB 3 hubs not backwards compatible? Maybe just this one
specifically? USB 2.0 devices like mice are not recognized when
attached. A USB 3.0 memory stick is recognized.
The attached Ethernet port is still not seen. Should rue(4) support the
