Description Cole Robinson 2015-10-13 22:29:14 UTC 
qemu has supported a usb3/xhci controller for a while, we should enable it for new enough OS. Hans once suggested windows 8 and later but I don't have the reference anymore. It will need some testing.

One thing to consider is that by default the qemu xhci controller only has 4 ports, but this is configurable at the qemu level. I imagine with virt-manager we would want to add more ports if there isn't any downside.

This bug tracks enabling it that toggle for libvirt:

Annotations are in libosinfo, and virt-manager has this now:
