Device 'usb-hub' could not be initialized Under ehci, after step 2: (qemu) device_add usb-hub,port=1,id=hub1 Warning: speed mismatch trying to attach usb device QEMU USB Hub to bus ehci.0 Device 'usb-hub' could not be initialized Based on above results, this bug has been fixed. Moving to ON_QA because Errata Tool did not do it
