Canon EOS 4000D failure to capture image (Error -110)

[aerotopografia]

Hi everyone.

I really love this software and I have it installed on two cameras (Canon EOS 1300D and Canon EOS 4000D).

In the case of the 4000D, it usually works fine for about a week (some 900 images), but then I get the following error:

*** 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') ***

After this has showed up I can't do anything other than rebooting the camera in order for it to work again.

I have on crontab the following command:

gphoto2 --capture-image-and-download

I am using gphoto2 2.5.20.1 and libgphoto2 2.5.22.1

Thanks in advance

can you try gphoto2 --reset perhaps if it hangs? perhaps that helps too.

aftre 900 images is quite a while. a debugtrace of right before that run and the buggy run would be interesting

[aerotopografia]

Sorry to answer so late. That camera was on a long-term exposure.

I've just managed to solve this issue using:
gphoto2 --wait-event=2s --set-config eosremoterelease=5 --wait-event-and-download=20s --filename /home/pi/Desktop/photos/IMG_%d-%m-%Y_%H-%M.JPG --set-config eosremoterelease=4

[msmeissn]

nice to hear it is solved. Not clear what the reason is sadly :/

[TheNeuralBit]

Note that the command #213 (comment) is bypassing the half-press to skip auto-focus, and just doing a full press of the trigger to capture an image only.

I'm running into this issue as well with an EOS 1100D, and it looks like #150 reports the same issue on a 1300D.

I haven't been able to capture my own debug log yet. FWIW it looks like #150 has a debug log of a failed capture, here's the relevant snippet:

0.394823 ptp_usb_getresp [usb.c:465] (0): PTP_OC 0x9110 receiving resp failed: PTP Device Busy (0x2019)

It's interesting that the error is actually coming from setting /main/capturesettings/aperture. In my case I'm also trying to repeatedly run gphoto2 with --set-config-index /main/capturesettings/aperture=%d --capture-image-and-download, and occasionally encountering this error. Perhaps setting the aperture is the issue?

[TheNeuralBit]

Managed to capture a debug log while this was occurring on my 1100D. The log doesn't seem to complain about setting the aperture, just the capture. I'll see if I can get a debug log for the last successful run before the buggy run as well.

[TheNeuralBit]

I captured a sequence of logs demonstrating the error. The last log (145504) ran into the "I/O in progress", the other two logs were the last two commands run before the failure (the same command, run 1 minute apart).

@msmeissn Does that provide any hint at what could be going wrong here?

[3Ddesignbros]

@TheNeuralBit Did you ever get this resolved? I have the same issue. I can only take one picture though then I have to turn the camera off and on again for the script to work again.

No it was not solved yet, 19.3.2021. Seems that you need to play with initial waiting sequence
gphoto2 --wait-event=300ms --set-config eosremoterelease="Press 1" --wait-event=1s --set-config eosremoterelease="Press 2" --wait-event=100ms --set-config eosremoterelease="Release 2" --set-config eosremoterelease="Release 1" --wait-event-and-download=CAPTURECOMPLETE --filename=/home/test/scp/$RANDOM.jpg

CANON 1300D the trick do --wait-event=300ms, but i am not success in no focus capture

[msmeissn]

i think the --wait-event=2s as first commandline option might be the thing, that we need to give the camera a bit of startup time.

[aerotopografia]

I used that command line at the beginning, and also to prevent the camera from jamming after a certain number of pictures, I use the - - wait-event=20s to give it enough time to full press the capture image switch just after that command line.

[msmeissn]

can you perhaps capture debug logs, one without the --wait-event=2s in the begin, one with it? so i can see what the trigger condition is to wait for

[Saadi2015]

I found a reason, I had the same problem "I/O in progress" with my EOS 1100d hanging after first capture with gphoto2.

It was the USB Cable connection to the EOS.
I used another one and then it worked.

[HappySeppel]

Hi everyone,
I had same problem and tryed out different proposed solution. In my Case the 4000D works fine with gphoto2 when the display is turn off. If I turn on the Display, the error appiers again.
Hope this helps

I have been getting the same error while trying to capture pictures with gphoto2 and Canon 5d Mark IV:
*** 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') ***

There is an option called mirror lockup. It is usually used to avoid blur when using telephoto lenses because they end up shaking the camera despite tripods. When I disabled the mirror lockup, I stopped getting that error.

My whole process of debugging the error is here:

It starts under July 26th.
