I forgot to include the answer to a previous question. The small circle in the upper right corner of a device definition that gets to the various device configuration screens is used from the initial Device view screen (Areas) of the Harmony client. These are device specific configuration screens rather than scene specific device screens which is why I think you do not see them from Scene management. Go back to the Areas screen to define specific device information.
