Not printing revision when it's zero is easy enough, but does your lspci -m
print -r info when it's zero?

(It would be so nice if there was some sort of spec for this...)

Dunno what the [00ff] in the Unclassified device is about. The string
"Unclassified" isn't in lsusb.c so it's getting that out pci.ids... yup. Which
means their code is ALSO special casing the zero there. (I mean I _can_ do that...)
