Cannon T7 PTP Device Busy

[btmccord]

I am having a issue with controlling a Cannon T7

When the camera is powered on the it executes the first command (ex. --capture-image-and-download) without issue. However when I run the same or any other command subsequently I get the following error.

pi@raspberrypi:~/gphoto2 $ gphoto2 --capture-image-and-download

*** Error *** Canon EOS Full-Press failed (0x2019: PTP Device Busy) ERROR: Could not capture image. ERROR: Could not capture. *** Error (-110: 'I/O in progress') ***

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 [email protected], please run gphoto2 as follows:

env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --capture-image-and-download

Please make sure there is sufficient quoting around the arguments.

The interesting thing is that if I run "gphoto2 --capture-image-and-download --debug" the command executes without issue.

The --reset command seems to have no effect

Having same issue, when I run subsequent capture-image-and-download or capture-image commands, e.g. gphoto2 --capture-image-and-download --filename=outputfile.jpeg, I get:

*** Error ***              
Canon EOS Full-Press failed (0x2019: PTP Device Busy)
ERROR: Could not capture image.
ERROR: Could not capture.
*** Error (-110: 'I/O in progress') ***       

But if I run, gphoto2 --capture-image-and-download --filename=outputfile.jpeg --debug --debug-logfile=my-logfile.txt, the command executes and I'm able to take a photo.
