I am a little confused, could somebody please clarify what is going on. I too have ordered a CEM 40 I guess it would be the 2021 version. Are you all saying that it does not have a USB port on the mount. Where is the USB port located then? I do not use a polar scope to polar align with ASI air pro there is no reason to even use it anymore. Am I going to have problems connecting this mounts to ASI air pro?Could somebody please provide some detailed instructions how to connect this mount to asiair pro? It has been my understanding that you were able to connect ASI air pro directly to the CEM 40 mounts without having to use the hand controller. Is that not true?. Are you all saying that the only USB port is the one that is on the I polar? Please clarify.
