See docs/ich9-ehci-uhci.cfg how that works in the x86 world. Using ohci instead of uhci works too. You need a single ohci controller only when setting the num-ports property to 6. Doing the same on sysbus needs some coding work to add masterbus + firstport properties and to wind up initialization accordingly. HTH, Gerd
