I might be totally wrong, but I suspect it will provide some logic
about where usb storage devices (sticks, disks, cameras) appear. At
the moment, if my machine has one internal drive then the first usb
device will appear as /dev/sdb, and /dev/sdb will only appear if
something is plugged in. So, I plug in a camera, it becomes
/dev/sdb. I unplug it and later plug in a disk - that too is now
/dev/sdb.
It also means that the nodes for disks match what is present: I have
an old-style DOS partition, /dev/sda1 is /boot (wasteful, but that
was how I started out), /dev/sda2 is an extended partition
containing /dev/sda{5..10} so udev creates nodes sda1, sda2, sda5,
etc.
Possibly also applies to usb printers (/dev/usb/lpN if I recall
correctly).
