cdparanoia and /dev/cd0

Just for the record, for some clueless noob in the future, I didn't
begin to have an inkling about what was going on until I stumbled upon
this thread:

https://lists.freebsd.org/pipermail/freebsd-questions/2011-December/236052.html

That discussion implies that both /dev/xpt0 and (some) /dev/pass[0-9]
needs to have the correct permissions set in
/etc/devfs.conf. Unfortunately I wasn't able to get the dynamic
configuration working by adding files to /etc/devd.

Maybe there might be a hint added to the Handbook in the section on
cdroms, when the cdrom is USB, that /dev/xpt0 and /dev/pass* need to be
addressed.

Now to understand the whys on cd-paranoia vs. cdparanoia.

Best,
Russell
