introspect error. window opens all greyed out

Hi,
Seems some similar questions have been going around I have an EN202 the one that's a simple thin rectangle with only one button. Silver and black it looks. From the questions and answers I saw before I think the key command is as follows:

~$ m210c connect
ERROR:dbus.proxies:Introspect error on :1.7:/org/codegrove/m210/daemon: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 1 matched rules; type="method_call", sender=":1.53" (uid=1000 pid=2102 comm="/usr/bin/python2.6) interface="org.freedesktop.DBus.Introspectable" member="Introspect" error name="(unset)" requested_reply=0 destination=":1.7" (uid=0 pid=815 comm="/usr/bin/python2.6))
