888LM incompatibility with Liftmaster 2255-2 chain drive opener

I'm posting this to help others that might come across this same issue. 

The Liftmaster model 2255-2 chain drive opener has a logic board that has a red pairing button.  This logic board IS NOT compatible with the 888LM controller and by association not comparable with the wireless gateway and MyQ.

So, when I contacted tech support they told me to buy the 821LM. Returning the controllers would be a hastle.

I was able to determine that the newer logic board (41AC050-1) is comparable with the 2255-2 model so for $85 I was able to upgrade the logic board (getting a purple pairing button) and it now all works with the 888LM and MyQ service.

I hope that helps someone.

Their compatibility chart says it is compatible but with an unexplained asterisk.
