I got a new EQ6 R with the USB port.
I had first light yesterday with it. Spent around 3 hours trying to resolve the issue (given some here saying the issues is resolved I thought I had some other issue). This is what I did:-
Updated the mount firmware to the latest version on SW website.
Followed the ZWO instructions at the top of this post. I used Win32 and the original SD card that came with my AAP. I just selected the AAP BOOT drive to install the new image and it overwrote the current OS.
Inserted back into the AAP. Reauthenticated online (I was concerned about this step but it was easy).
When I turned on the AAP and connected my tablet it updated to the most recent firmware. I was worried this would undo the new image, but it seemed to work. Obviously this version has some additional drivers that remain even with firmware updates.
Mount connected via USB under EQmod with 115000 baud.
