Hi! I noticed that QMP's "device_add usb-ehci,id=i2,bus=pci.0" fails on PCI hotplug. The same for pci-ohci and this is because their initfn() do "dc->hotpluggable = false". So I removed those and now I can hotplug USB hosts but none of them is able to actually work:

Is QEMU just missing some bits or there is some fundamental issue which I just do not see? Thanks! -- Alexey
