Description of problem: ccid controller can not be attached to usb hub Version-Release number of selected component (if applicable): libvirt-3.9.0-7.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. prepare guest xml with 1 usb3 controller, and 3 devices connected to the controller. # virsh dumpxml pc <controller type='usb' index='0' model='nec-xhci'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </controller> ... <input type='tablet' bus='usb'> <address type='usb' bus='0' port='1'/> </input> <redirdev bus='usb' type='spicevmc'> <address type='usb' bus='0' port='2'/> </redirdev> <redirdev bus='usb' type='spicevmc'> <address type='usb' bus='0' port='3'/> </redirdev> 2. edit the xml to add 1 ccid controller and 1 usb disk # virsh edit pc ... <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/pc-2.qcow2'/> <target dev='sdx' bus='usb'/> </disk> <controller type='ccid'/> ... As usb3 only support 4 ports, a hub will be added, and the usb disk and ccid controller will attached to the hub # virsh dumpxml pc ... <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/pc-2.qcow2'/> <target dev='sdx' bus='usb'/> <address type='usb' bus='0' port='4.1'/> </disk> <controller type='ccid' index='0'> <address type='usb' bus='0' port='4.2'/> </controller> ... <hub type='usb'> <address type='usb' bus='0' port='4'/> </hub> 3. guest can not start # virsh start pc error: Failed to start domain pc error: internal error: process exited while connecting to monitor: 2018-01-05T08:10:12.703102Z qemu-kvm: -device usb-ccid,id=ccid0,bus=usb.0,port=4.2: usb port 4.2 (bus usb.0) not found (in use?) Actual results: ccid controller can not be attached to usb hub Expected results: guest can start successfully, or there is error message about ccid controller can not attached to usb hub Additional info: If there is 2 usb disk with adress like <address type='usb' bus='0' port='4.1'/>, <address type='usb' bus='0' port='4.2'/>, the guest can start successfully.
