Yes, that's my interpretation too. You did test an UHCI controller, I think, but I don't remember---did you test an EHCI controller without companions, using something like "-device ich9-usb-ehci1,id=myehci -device usb-keyboard,bus=myehci.0"? If that works, the issue would be specific to EHCI companion controllers. If that doesn't work, there is at least a generic in the EHCI driver---of course there could possibly be another in the companion controllers, but I'd try getting EHCI alone to work. Paolo
