Description of problem:
Usb input device attached to the same hub with usb-storage  can't work after local migration

Version-Release number of selected component (if applicable):


How reproducible:
100%

Steps to Reproduce:
1.Boot up guest with command:
/usr/libexec/qemu-kvm \
 -m 8192 \
 -smp 4 \
 -monitor stdio \
 -vnc :91\
 -vga std\
 -nodefaults \
 -device virtio-blk-pci,drive=drive-virtio-blk0,id=virtio-blk0 \
 -drive file=rhel74-64-virtio.qcow2,format=qcow2,if=none,id=drive-virtio-blk0,snapshot=on \
 -device virtio-net-pci,netdev=net0,id=nic0,mac=52:54:00:c4:e7:84 \
 -netdev tap,id=net0,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown,vhost=on \
 -device qemu-xhci,id=controller1\
 -device usb-hub,id=hub1,port=1 \
 -device usb-mouse,id=usbmouse,port=1.1\
 -device usb-kbd,id=usbkbd,port=1.2\
 -device usb-tablet,id=usbtablet,port=1.3\
 -device usb-storage,id=storage1,port=1.4,drive=drive1 \
 -drive file=data1.qcow2,id=drive1,if=none \
2.Boot up destination guest with additional command:
 -incoming tcp:0:7777
3.Try to migrate it on localhost.
(qemu) migrate -d tcp:localhost:7777

4.Try to use mouse and kerboard in destination guest via vnc after migration.

Actual results:
Cann't use the usb input device(usb-mouse ,usb-tablet,usb-kbd)

Expected results:
Can use the usb input device(usb-mouse ,usb-tablet,usb-kbd)

Additional info:

The same issue on x86 platform ,and only happened with nec-usb-xhci and qemu-xhci controller.

That BZ is marked a Regression, so should be this one?

According to https://bugzilla.redhat.com/show_bug.cgi?id=1451631#c27 this build fixes that BZ. Hopefully they're duplicates indeed, we need to validate.
