I replied to your query earlier; however, your question inspired me to write a
new wiki entry:
This entry only covers one method of approaching this problem (namely, using
udev to create unique device filenames). Other approaches are possible and
may be simpler to configure in some (perhaps many) cases. Still, the udev
approach is extremely flexible.
