"Device busy" error after 32 captures with Fuji XT-3

[Prototypers-lair]

Hi everyone, Absolutely love the active community on this project.

I have my Fujifilm XT-3 set up to photograph time-lapses on Octolapse using a Gphoto2 script. The setup works, but after exactly 32 captures, I get an error saying the device is busy. I've varied the command, interval timer, and image quality. I've tried capturing and downloading, with and without --keep, I've tried only capturing, and I've tried the trigger-capture option. I've tried capturing by hand, and with the script described on this page I always get this error after 32 successful captures:

2021-05-12 18:13:41,737 - octolapse.script - ERROR - Error output (stderr) for 'Fuji XT-3 - Snapshot Camera Script':

*** Error ***              
PTP Device Busy
ERROR: Could not capture image.
ERROR: Could not capture.
*** Error (-110: 'I/O in progress') ***

I'm not sure if this is a bug in libgphoto2, or a bug in the camera.

Name the camera Fujifilm XT-3

libgphoto2 and gphoto2 version gphoto2 2.5.27 gcc, popt(m), exif, no cdk, no aa, jpeg, no readline libgphoto2 2.5.27 standard camlibs (SKIPPING lumix), gcc, ltdl, EXIF libgphoto2_port 0.12.0 iolibs: disk ptpip serial usb1 usbdiskdirect usbscsi, gcc, ltdl, EXIF, USB, serial without locking

To Reproduce

Perform >32 captures from the command line or script with the combination of the above versions, and a Fujifilm XT-3 running 4.1 firmware. I use this script (rename to .sh) to trigger 33 images consecutively, it fails at the 33rd every time test.txt my-logfile.txt

@msmeissn Hi Marcus,

Its me again. I have a Fujifilm GFX100s

Model Port

Fuji Fujifilm GFX 100S (2nd) usb:001,014

I have the following versions:

gphoto2 2.5.28 gcc, popt(m), exif, cdk, no aa, jpeg, no readline libgphoto2 2.5.28 standard camlibs (SKIPPING docupen lumix), gcc, no ltdl, EXIF libgphoto2_port 0.12.0 iolibs: disk ptpip serial usb1 usbdiskdirect usbscsi, gcc, no ltdl, EXIF, USB, serial without locking

Its working like a charm. however it can not take more than 10 image in one go either with --capture-image or --trigger-capture. I get the same "PTP Device Busy" error

*** Error ***
PTP Device Busy ERROR: Could not trigger capture. *** Error (-110: 'I/O in progress') ***

This is my observation that as soon first image is taken, camera goes in to busy state. which can be seen from Blinking orange and green indicator lamp. I know this could be because of the camera as it is in a busy state, but is there any way I can disconnect the camera when its not taking picture

I am using the following code to mimic AEB as it changes the shutter speed after taking each picture

`# AEB

import RPi.GPIO as GPIO

import logging import os import subprocess import sys import gphoto2 as gp

GPIO.setmode(GPIO.BCM) GPIO.setup(22, GPIO.IN) GPIO.setup(22, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)

while True: if GPIO.input(22):

    from subprocess import call
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=30s"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=15s"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=8s"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=4s"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=1s"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=1/2"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=1/4"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=1/8"])
    call(["gphoto2", "--trigger-capture"])
    call(["gphoto2", "--set-config", "shutterspeed=2s"])`

i think you will need to download the images always immediately, as they are stored in camera RAM and that runs full.
