[vfio-users] RocketRaid 1144c / AsMedia 1042a

[Nick Rodgers]

Just realized that the pastebin shows the AsMedia devices being bound to
xhci_hcd, I stopped using the vfio-pci driver on those devices temporarily
so I could pass through the usb devices until I resolve this issue. If that
makes a difference in troubleshooting, please let me know.
