I'd just use the formatted address syntax shown by lspci/lsusb, eg

  USB      001:002
  PCI      0000:01:3f.0

Given the PCI / USB address you ought to be able to use the host 
device enumeration patches to find the matching device on the host.
Once you have that you get the friendly Vendor + Product name 
which would be more useful to display
