I'm using the latest version of kStars 2.9.3 under OSX10.12.4 and I'm having trouble connecting my QHY5LIIC camera to it. It works just fine on my Pi so I know that the camera and cable are okay. If I plug in the camera and fire up kStars EKOS gives an error "Unable to establish: QHY CCD".

Here's where it gets strange. If I open PHD2 first and connect to the camera from there, then disconnect then open kStars, everything works. I can connect to the camera just fine and take pictures etc. However, as soon as I unplug and replug the camera, I have to go back to PHD to get it working again. It kind of feels like it must be a driver issue but I'm at a loss for how to fix it. Can anyone help?
