#1044 Canon 2000D - Error (-110: 'I/O in progress')

[Rafal Mantiuk]

During "--capture-image-and-download" for Canon 2000D gphoto2 typically ends up with " Error (-110: 'I/O in progress')" (log attached).

In some rare instances a picture is orrectly taken in downloaded, but most often the error above is reported.

[Marcus Meissner]

can you try insertign a short wait before the capture:

gphoto2 --wait-event=1s --capture-image-and-download

or perhaps 2s if this makes it more reliable?

[Rafal Mantiuk]

The error appears to be that the camera cannot buffer commands and so capture fails when IO between the camera and PC is taking place. As this takes an indeterminate amount of time no amount of waiting between shots will fully resolve the problem.

might be fixed in 2.5.31
