[vfio-users] Passthrough USB PCI Controller

Does anyone know of an easy way to pass through a USB PCI controller in
QEMU w/o libvirt? Since libvirt automatically binds the controller to VFIO,
without it I get VFIO not found error messages.

I am getting slightly better performance with a QEMU script rather than
using virt-manager. I cannot bind them on boot since I have the same id for
all USBs.
