Fuji GFX 50 R incorrect work of "capture-tethered" mode

[NovoMar]

Describe the bug

Hi everyone. I use Fujifilm GFX50R camera and try capture-tathered mode.

I'm trying from console sudo gphoto2 --capture-tethered --force-overwrite - it works only if I take one or more photo before. Then I get in console:

sudo gphoto2 --capture-tethered --force-overwrite

Waiting for events from camera. Press Ctrl-C to abort.

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-tethered --force-overwrite

Please make sure there is sufficient quoting around the arguments.

If I try other command gphoto2 -I 20 -F 1000 --capture-image-and-download --filename "%Y%m%d%H%M%S.jpg - it works fine

If I try capture-tethered mode from shell and put release button every second I get in console:

*** Error (-1: 'Unspecified error') ***

I'm shutting every second and when I get this error I simply restart capture-tethered command it works for me, but I'm looking for right solution. Can you help?

i did a safety fix for this for testing

msmeissn, thank you so much

I rebuild with changes from your commit and I get next results. When I take one photo and then run --capture-tethered --force-overwrite and then put release button - I get the same error (like in my issue) If I run --capture-tethered --force-overwrite and put release button simultaneously - it works fine. If I run --capture-tethered --force-overwrite before release button - Fuji doesn't respond on button.

My log file is very long. How can i share for you?

[msmeissn]

i think big file sharing can be done via drive.google.com :/
