I have issues connecting 2 ZWO Cameras to Ekos with the latest version. I'm using a Asi533MCPro for imaging and an ASI 120mini for guiding, most of the time with PhD but sometimes using the internat guider.
In the previous version that I used (3.6.5) everything was connecting fine. In the image train I had to set ZWO camera 1 (imaging) or ZWO camera 2 (guider).
In the latest version I can only choose ZWO camera and only the 120mini appears.
An additional test with an StarlightXPress Lodestar leads to the same result, the 533 is not connecting.

Any idea how to fix this.

To me this looks very much like what has been reported by Andrew Jeffries here: indilib.org/forum/ccds-dslrs/14176-using...ras-with-kstars.html
