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. cheers, Gerd
