When there are multiple usb devices being attached with same
vendorId and productId, virt-manager failed to distinguish
them.
The patchset makes virt-manager use <address> to distingush
multiple usb devices as follows:

  <hostdev mode='subsystem' type='usb' managed='yes'>
    <source>
      <vendor id="0x15e1"/>
      <product id="0x2007"/>
      <address bus='5' device='19'/>
    </source>
  </hostdev>

When there is unique usb device, the xml is like:
  <hostdev mode="subsystem" type="usb" managed="yes">
    <source>
      <vendor id="0x15e1"/>
      <product id="0x2007"/>
    </source>
  </hostdev>
