Hi Again Everyone,
Just an update to my last post. As noted above, I have current Java, current CFM and the serial-USB driver installed on Windows 10 and hooked up my AVX with Starsense as per the picture in the first post of this thread. Today CFM found and recognized my mount, the hand control and Starsense showing all firmware up to date. As others have pointed out I believe you must have the serial driver installed even with the mini USB hand control in order for CFM to work. Also, it took about 30 seconds for it to find Starsense so have a bit of patience!
Thank you again to everyone who contributed to these threads, if you follow the advice, updating your firmware is a simple and quick exercise.
