Hi,

Now *that* is really strange, especially as UHCI1 is pci function 0,
without probing that successfully you wouldn't see the other pci
functions (1+2+7 for uhci2+uhci3+ehci) in the same slot in the first
place.

Try '-device usb-mouse,port=5 -device usb-kbd,port=6'. That links mouse
+kbd to the ports which are routed to uhci3. Which of course also only
papers over the root cause. But should do as workaround for the time
being and is also a useful data point.
cheers,
Gerd
