The devmon mailing lists are available from the sourceforge page.

Which "instructions"? Devmon ships with an INSTALLATION file, and a USING 
file. I really can't see what is missing in the documentation, and unless 
you're more specific about which documentation you followed, I can't improve 
it.

I assume you've run --help, which lists:

Usage: devmon [arguments]

  Arguments:
   -c       Specify config file location
   -d       Specify database file location
   -f       Run in foreground.  Prevents running in daemon mode.
   -p       Print message.  Don't send message to display server.
            print it to stdout
   -v       Verbose mode.  The more v's, the more vebose logging.
   --debug  Print debug output (this can be quite extensive).

  Mutually exclusive arguments:
   --readbbhosts   Read in data from the BigBrother/Hobbit hosts file
   --syncconfig    Update multinode DB with the global config options
                   configured on this local node.
   --synctemplates Update multinode device templates with the template
                   data on this local node.
   --resetowners   Reset multinode device ownership data.  This will
                   cause all nodes to recalculate ownership data.

I don't use this myself, and running it every 5 minutes is a bit excessive. I 
assume you are aware that this does *nothing* besides update the hosts.db 
file, it doesn't actually poll any devices.

Is this file writable by the user that runs devmon?

Same question here.

Did you actually *start* devmon?

A sample init script is provided in the extras directory. This is covered in 
points 6 and 7 of the INSTALLATION file ...
