I have Ubuntu 20.04 on ARM64 board with INDI-FULL/KSTARS.
EKOS connects successfully to my ZWO ASI MC071 pro camera.

I have set values for both GPSStartLine/GPSEndLine to zero as suggested by this post:
indilib.org/forum/ekos/14152-my-asi1600m...stopped-working.html

When I initiate an exposure nothing happens and after some seconds INDI control panel message says retrying a new capture.
The log file shows:

- "ZWO CCD ASI071MC Pro ist verbunden."
- ZWO CCD ASI071MC Pro : "[DEBUG] Snopping on Mount iOptron GEM28 "

I tried the camera with another capture application and can confirm that the camera works flawlessly...

I checked all ZWO xml-configuration files in the .indi directory and all files show GPSStartLine/GPSEndLine = 0, also
in the INDI control panel I have GPSStart/EndLines=0 in the camera's control tab.

I have attached the indi-log-file for more information.

Has anybody ideas what to do to get the camera capture process to work?

Any hint is appreciated,
Thanks

Ensure you have power connected to the camera.

I large percentage of issues like this end up being USB related. A bad USB cable or a USB hub causing issues.

Sorry, but it's not an issue regarding power supply. If I use the same USB port in combination with another capture
software from ZWO (ASIAIR) the camera works flawlessly. Something has changed with regard to INDI drivers,
the log tells me that the camera is connected but after starting the exposure the driver does not get exposure status...

This is a new issue affecting ZWO cameras with the latest INDI driver. I believe Jasem is looking into it.

In the meantime get an older version. I’m running an older Mac version and it works again.

I 4 weeks have passed since my ZWO cameras do no longer work with latest INDI Lib.
I today did an apt-get update but can confirm that ZWO cameras still do not work.
Is there no progress on this issue?
Is there a workaround available?
Any hint is highly appreciated,

Clear skies,
Helmut
