Indi is recognising your camera - it said so in the log. Are you up todate on Indi/Kstars version wise ?
Do you use Bleeding edge version of Kstars/Indilib ?
Did you try and get Gphoto command line to take a simple image - what was the result ? If it failed run the same command with debugging on - it may shine the light on the problem.
As the camera IS being recognised by Indi I think you need to switch on verbose logging on ALL subjects even if you dont use them.
My gut feeling is :
1. Something is still connecting to the Camera hence Indi can see it but doesn't connect - should appear in one of the logs or in the Indi Satus bar if you manually connect (i.e. switch off auto connect)
2. Your camera settings are wrong before it connects which although the camera is being found it is failing to connect - check camera Res,etc settings in the camera configuration file. Its not like Windows software (APT etc) which puts in the details for you - Yo are probably aware of tha but just saying
3. Your camera isn't supported in the version of IndiLib you have loaded so it knows its a Canon Camera via the DEV signature but the ID of the 200D isn't set up yet - hence I asked if you are using "Bleeding edge" - if not try it - notes on forum.
Think you need more expertise so hopefully one of the developers might help - hope you get sorted - its worth it - I took 12mths to sort my problem out with my 100d - and it was with a setting on the camera NOT Indi LOL. Clear Skies
DOES ANY ELSE USE a 200d with Indilib - question to other members ??????
