Unplugging ZWO Camera from PC hangs CPWI Software..

O6jj6geV

I have a Celestron AVX mount, C6" OTA and C9.25" OTA.

I have a MeLE Mini PC connected to the mount and access the mini PC using Windows Remote Desktop.

I use SharpCap 4.1 and Celestron's CPWI to control the mount via the hand controller USB + (Ascom Platform is installed)

I use ZWO ASI cameras.
Everything works well but just lately I find that If I unplug my ZWO ASI294MC camera the CPWI software freezes.

I've never had this issue before. I've been able to swap cameras in the past, but now as soon as I unplug the ZWO camera the Celestron CPWI software HANGS.

I have to restart everything to begin working again. SharpCap isn't even running yet and the camera is pluged into the MeLE mini PC. It doesn't make sence that unplugging the camera is hanging CPWI since that software isn't using the camera.

Anyone have a clue?

That's a strange issue, especially since CPWI shouldn't be affected by plugging a camera that it's not even interfacing with.
1.Check Device Manager > USB Controllers
See if your ASI camera and Celestron hand controller show under the same USB hub. If so, try separating them:

Use a powered USB hub for the camera.
Plug the hand controller directly into the PC.

2.The ASI driver or ASCOM platform may have triggered a system-level event that CPWI did not handle properly. When CPWI is communicating with the serial port via ASCOM, sudden changes in the device may cause the program to hang.
