G'Day,
with a problems like that, there are a few possibilities, try narrowing it down by changing the operating conditions for the camera and see if you get any change that could then lead you to a more specific diagnosis...
I'd try....
- Changing the camera driver
- Changing the PC or laptop you are using
- Disconnect the camera from the hub and try it directly
- Operate unit with 1 ultra short USB cable, perhaps the one supplied by ZWO
- Try other imaging software, perhaps the ZWO supplied
- Check heatsink temperature - if the sensor is 20-30°C above ambient then the otherside of the peltier cooler (the heatsink side) would be VERY HOT. maybe even use an non contact thermometer if you have or can borrow one, just to get a sense of whether the reported sensor temperature is ridiculous or plausible.
- You checked the DC voltage from your power supply. Also check for any significant AC component on the output
If you have a lab power supply with an adjustable current limit, what was it set to, whilst experiencing these issues? On the rear of the camera ZWO specifies 12V @3A as required, but in other ZWO literature I have also seen 11 to 14V at 3 to 5A recommended.
See ZWO details here....
In respect of the power supply, that of course doesn't explain why things may have been OK in the past, but not now, .... but who knows, something has changed.
Best
