Especially since mknod is well documented and udev is not.  Grr.
Fortunately, for scanners you can usually just copy an existing rule.

But there is a secret way to use the old simple mknod: create the
node in /lib/udev/devices/ rather than /dev, and udev will create it
in /dev on every boot.

It's possible they'll remove that at some point ...  but for now
it's an easy way of cheating if you know the node you want and don't
want to spend days debugging a custom udev rule.
