Red Hat Bugzilla – Bug 1249460
inventory shows 0000:0000 for USB root hubs on HP rx1620

Need to figure out if there really is no USBIDs for these devices (are they just emulated/virtual perhaps?). Either fix lshw to report the USBIDs properly or make beaker-system-scan exclude 0000:0000 from USBID key-value.
The USB root hubs are essentially virtual, they seem to be an abstraction created by the kernel to manage all the USB devices attached to a PCI USB host controller.
In newer kernels they have a USB id like 1d6b:0001, but in the RHEL5 kernel the vendor and product really are hardcoded as zeroes instead:
It's possible that beaker-system-scan (or lshw?) should just be filtering out these root hubs which are not real devices. I'm not sure if that's the best answer or not. It probably doesn't hurt to include them as we are now.
It looks like we should just make beaker-system-scan leave out USB devices from the USBID key when the ids are all zeroes as in this case.
Beaker 21.1 has been released.
