A hub is a device that expands a single port into several so that there are more ports available to connect devices to a host physical machine system.
To specify the hub devices configuration settings, use a management tool to make the following changes to the domain XML:

  ...
  <devices>
    <hub type='usb'/>
  </devices>
  ...
