When I try to take an automatic picture with my SLR camera (Canon Rebel XT) via the following command in gphoto2:
gphoto2 --trigger-capture
It returns an error as follow
*** Error ***
Sorry, your camera does not support generic capture
ERROR: Could not trigger capture.
*** Error (-6: 'Unsupported operation') ***
For debugging messages, please use the --debug option.
Debugging messages may help finding a solution to your problem.
If you intend to send any error or debug messages to the gphoto
developer mailing list <gphoto-devel@lists.sourceforge.net>, please run
gphoto2 as follows:
env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --trigger-capture
Please make sure there is sufficient quoting around the arguments.
To resolve that I tried to find (and kill) any other ongoing gphoto2 process, but I couldn't find any:
ps -A
I also checked if the camera is properly connected and recognized by Pi3 via:
pi@raspberrypi:~ $ gphoto2 --auto-detect
Model Port
----------------------------------------------------------
Canon EOS 350D usb:001,016
Another fact that might be helpful to troubleshoot this is that when I connect my LSR to Pi3 it says "busy" on its screen.
Thanks you!
