20.16.11. Hub Devices

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>
  ...

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

The hub element has one mandatory attribute, the type whose value can only be usb. The hub element has an optional sub-element address with type='usb'which can tie the device to a particular controller.
