I ended up flashing a new SM OS onto a new SD card and everything is running as it should now. QHY cameras are all recognized and connect via USB and KSTARS. Something must have gone wrong during an update I guess, I really don't know what caused the issue. Any who, problem solved.

Hi Tom,

Yes, I followed the steps above in the device manager but with each of the drivers it said "the best drivers for your device are already installed. I verified the firmware version of the camera did not change.

Thanks, Dalton

Hi Tom, thanks for the guidance. I downloaded the QHYCCD Windows all in one pack along with EZ Cap on my laptop. The install went smoothly, brought up EZ Cap, plugged in the cameras and it connected immediately. I verified with both QHY5 and the QHY168c and they both came up and were able to capture test frames. Does that mean my camera and drivers on camera are ok? If so it does seem like something on the Stellarmate OS/RPi4.

I did a factory reset hoping that would resolve things but still can't recognize the QHY cameras in Kstars. Since it seems to be squarely centered on the RPi, is there a way to verify that I have the correct drivers, or do a clean re install? I suppose I could flash the Stellarmate OS to the sd card again and really start anew, but I'd like to avoid that if possible.

Hi Tom, I seem to be having a similar issue. None of my QHY (QHY168c, QHY5LIIm, QHY Polemaster) equipment is showing up in Kstars, but I do see them in lsusb and dmesg (RPi4, Stellarmate OS). Can you expand on how you found the answer to your problem and getting kstars to recognize the camera?

Looking for some guidance, (I use stellarmate OS on my RPi4). Have had little to no issues before last night with the RPi4 recognizing my cameras and mount via USB, but as of last night right before the meridian flip it no longer recognizes the QHY cameras (QHY168c - USB interface and 12V power and QHY5L II M - direct power and data from USB). It does however recognize the Nexstar + hand controller for my CGX L, but only when that is the only USB plugged in, not when cameras + mount are connected.

For troubleshooting, I have tried using different cables, tried using just one camera and no other USBs, have tried turning on/off, unplugging and re-plugging everything, checked for updates. Nothing on the RPi4 is indicating low power from the adapter.

I thought perhaps it might be a USB power consumption issue (even though I haven't had issues in the past), so I got a powered USB hub with an external adapter and the same issues arise; no recognition of the QHY cameras but the Nexstar HC is recognized through the hub. Makes me feel less like it is a USB power issue with that being the case.

I guess my next plan is to get a new power adapter for the RPi4, maybe overall there isn't enough power to the board?
Any other ideas or thoughts on troubleshooting? Any other details I can help provide?

Quick edit;

I had a ASI290mm mini that came in a couple days ago. I tried that out in both USB 2.0 and USB 3.0 ports and the RPi4 recognized and connected. Seems like the issue is isolated to the QHY168c and QHY5L II M? I noticed the red light on the QHY5L II M doesn't come on either, indicating that power isn't being received.
