The serial Crestron Certified Driver for the 32" frame has this note in the definition:
To work properly the Sub-micom Version of firmware needs to end with 1040 or higher. Samsung provides firmware updates.
The publicly available firmware updates don't seem to update the sub-micom version, only the micom version (mine is on 1003). I don't know if this is a red herring or if there is actually a newer version available somewhere.
