The dump from Josh shows, that the uaccess udev property is properly
set. So I don't think it's an udev rules ordering issue.

I think the problem rather is, that you are already logged in and the
ACLs are only applied on login or when the session becomes active.

I assume if you log out and re-login after the hotplug, the ACL is
properly applied?
