Public bug reported:
With Trusty 14.04 LTS documentation suggests that when attaching a Host
USB device that
virsh nodedev-list --tree
can be used to gather the values required for the XML <address> element
such as:
<hostdev mode='subsystem' type='usb' managed='yes'>
<source>
<vendor id='0x8564'/>
<product id='0x1000'/>
<address bus='2' device='6'/>
</source>
<alias name='hostdev0'/>
</hostdev>
However, it does *not* report the device ID, which is required and critical.
$ lsusb
Bus 002 Device 006: ID 8564:1000
E.g: Shown by virt-manager, this is USB Bus 2, Device 6:
+- pci_0000_00_1d_7
