Yes.  devices don't just show up and stay there any more.  They
are managed by devfs.   I haven't studied that to see just how
it works yet, so I don't know at which point it should start showing
up in /dev if ever.

I just figured trying a newfs with the /dev/r... might be something
to try out to see what happened - sort of an experiment and if that
doesn't do it, then maybe the thing to pursue is your concern about
the cables.

If that doesn't work, I think this has gone beyond any problems I have
ever had so I don't know what else to suggest.  Hopefully someone else 
will have some thing to say.
