Have you tried a "virsh detach-device ..." and then the corresponding [re-]attach (or maybe even just a new "attach" first)?
When my guest complains about the USB not being there I can generally make things work with:
virsh attach-device <guest> --file usb_device.xml --current
all sorts of combinations like that,.
where the "usb_device.xml" file has the six lines you included above from your "virsh edit". Since your guest isn't running I think you'd have to use "--config", rather than "--current" on that line.
It's not obvious that that will clear up your assignment problem, but it might be worth a shot.
turned out, after hours of head banging, I needed to do a --force-start
virsh start mydomain --force-start
and voila, no problems, USB device picked up at its new address, etc.
