That applies to windows 7 only, which is EOL next year.
win7 doesn't ship with xhci drivers, but you can download and use
nec/renesas drivers which require nec-usb-xhci.
win8+ ships with generic xhci drivers which works with all xhci
hardware, including qemu-xhci.
So it indeed makes sense to refer to qemu-xhci.
