Description of problem:
Libvirt does not generate addresses for USB host devices. For almost every other device (even PCI host devices), an address is generated and can be read via parsing domain XML.
Version-Release number of selected component (if applicable):
rpm -q libvirt
Steps to Reproduce:
1. Create a domain XML containing valid type="usb" hostdev
2. Start the domain
Domain XML contains hostdev element without additional address child.
Domain XML should contain hostdev element with libvirt-generated address child.
Since there's already a RHEL bug tracking this, there isn't much utility in keeping this report open. Duping to the RHEL bug
