some ideas of what can we do to identify the exact problem?

You said you use linux and then on console shows MacBookPro? so which is which?

Yes, sorry for not be clear, we test the camera in a Linux OS mounted in a MacBookPro, and in other computer (asus) whit Linux too, but we get the same results

You should try in OS X KStars on the MacBook Pro in a local indiserver and see if you get the same results.

We dont have OS X available. We want use Linux 16.04 LTS to control the camera canon T6i and a Meade telescope. So far we have been able to control the telescope, but the camera is not reachable yet. A further step will be to have all controls though a raspberry pi, but we need to be able to control the canon dslr.

We managed to get a different problem (not sure it is an error yet). Here I attached two screenshots and a log file on the start up of the Kstars control system.

The camera has a full battery, it is in manual mode, no other software is being used or is loaded, darktable was used to test the camera and got pictures, console commands were able to take photos too.

Try this and post the debug file:

Hi,

We run the command as you say:
gphoto2 --debug --debug-logfile=gphoto.txt --capture-image-and-download

The log file zipped is attached.

Hmm it appears OK, however, the libgphoto2 version is a bit old. Try to use a more recent version from the PPA:
Then try the driver again.

Hi, We update the libgphoto2 as you say, and we still get the same problem, the logs:

The camera is connected, battery full, manual mode, and darktable can use it normally but is close.

we attach the log file of the command:
gphoto2 --debug --debug-logfile=gphoto.txt --capture-image-and-download

Log file shows you're still using libgphoto2 2.5.9 for some reason...

FWIW I had the same problem with Canon t6i and this fixed it right up.

Cheers,

Stephen
