Are you logged in under a different user? Those lines only grant
access to the root user. I'd suggest you check to be sure they still
refer to the same device name, and that they match the user you're
logged in as. Also make sure to restart the dbus service after your
changes.

Someone who knows dbus better than I could probably recommend a better
place to put the permission changes. Might need to do some research on
that.
