Hmm, so you've both an amd xhci and an etron xhci chip. Do you know to
which xhci the port you're trying to use belongs ? And can you try
with a different usb-3 port ?

I've access to an Etron EJ168 controller, since I specifically bought
one to try and deal with the fact that there quality is, erm, somewhat
lacking. So if this is with the Etron controller I can try to reproduce.

Note I'm about to drop of the internet as I'm going on vacation, I'll be
back Mon 25 Aug.
