Not sure what you mean by limit the output to a device.  Do you mean
see the relevant bits of dmesg?  Is so then run dmesg with the card
out and see what the last messages are.  Plug the card in and run
dmesg again.  See what has been added.

I presume you mean that it is showing Me as the owner and Gary14 as
the group, both with full permissions so that is ok.  I presume you
mean that it will not let you modify the permissions for the user or
the group, but since those are stored on the card that is not
surprising if it has mounted read only.
