SMD channels are created by the remotes in "opening" state, but sometimes as we close and try to reopen them they linger in closing state. Following the search for a matching channel the create_ept() will verify that the channel is in a suitable state, so we can lax the restrictions of the search function to work around above difference in behaviour.
