Question: MiSTeryNano MIDI shield for Tang Nano 20k

[jfceklosky]

I just had a few of these made by JLCPCB

https://github.com/MiSTle-Dev/Boards/tree/main/misteryshield20k

I have the MSO dock programmed (1.4.10) and plugged into the board along with the TANG 20K programmed with

https://github.com/MiSTle-Dev/MiSTeryNano/releases/download/v1.2.9/atarist.fs

The TANG onboard BL616 was also programmed with 1.4.10.

The ST boot and works fine as long as I use the hub plugged into the TANG, but when I try to use the hub on the MS0 dock, I get no keyboard or mouse. I tried the db9 with a known good ST mouse but that also fails.

If there anything special I need to do when using the misterryshield 20K with the MS0 dock?

I had a second MS0 dock and this one works just fine.

I guess I have a bad dock. I did clear the programming on it and reflashed it, but it still does not work. Also the ST does not want to boot from the HD image when it is connected.
