I'm a little bit at a loss here, as I can't find anything in the vdev
tree dealing with, say, scanners or, say, mode switching USB devices.
Since those are major chunks in udev rules, I'm just confused. Have I
misunderstood?

I find "scanner" mentioned in the hwdb, but there is no formal
classification of those other than identifying as usb (or pci); nothing
classifying them as scanners (unless you'd regard the model label as
such). I wish someone could explain things for me...
