Can not capture image when camera keeping power on all the time during computer startup
Thanks to gphoto2. Thanks to Marcus, could you please help me on this situation. This problem only occurs in this particular situation. I am not sure whether it is a bug, I search for a while but I don't know how to fix it without touching the power knob of camera.
Describe the bug The camera can not capture image is the case of : (the camera is turned on before the computer start) AND (the camera is keeping power on). If the camera is turned off and on again, capturing image is normal and everything goes fine. I can not touch the camera power knob in the photo-taking job so I have to keep the camera power knob on all the time. I have a AC power adapter as a faking battery to keep power on, but the genuine battery has the same problem.
Name the camera gphoto2 --auto-detect gives: Sony Alpha-A7R III (Control) usb:003,002
libgphoto2 and gphoto2 version gphoto2 2.5.23 libghoto2 2.5.23 libghoto2_port 0.12.0
OS and software environments OS: Ubuntu 19.10 and ArchLinux 2019.12 No gvfs related process in background (X window not installed or reboot into multi-user.target so X window not started) lsusb gives: Bus 003 Device 002: ID 054c:0c33 Sony Corp. ILCE-7RM3
To Reproduce
- power off computer and camera
- Connect USB to computer
- Turn on camera (never turn off in the following steps)
- turn on pc
- gphoto2 --auto-detect can find the camera
- lsusb can find the camera
- gphoto2 --capture-image gives: *** Error *** PTP Timeout *** Error *** An error occurred in the io-library('Timeout reading from or writing to the port'): No error description available ERROR: Could not capture image ERROR: Could not capture
If its a camera misbehavior, attach debug output using --debug --debug-logfile=debug.log (if considered useful).

Thanks, seaquel
The trace itself shows the camera is not reacting (timing out) to even the first commands.
Soemthing might be causing this if it is enabled during boot, but not clear what.
Can you try if "gphoto2 --reset" helps as workaround?
Thanks for your reply.
I tried "gphoto2 --reset" but no difference.
I guess something happened during the boot. But I tried a minimal Linux system (minimal ArchLinux system without X window or other big packages) but no luck. So I don't know which one communicating with the camera and gphoto2 failed to write to the usb port.
One simple solution is to plug out the camera USB cable and in again, then "gphoto2 --capture-image" and any other gphoto2 command works smoothly. Based on this, my workaround is using a USB hub (with a on/off switch) between camera and pc. After the pc and camera boot successfully, I switch off and on the USB hub through a home made small circuit board remotely. The problem is solved without touch any physical button or knob.
Same problem here, with a Sony Alpha 6400. gphoto2 --reset does not work. Power cycling the camera does work, however. But it seems impossible to get a connection with the camera connected and powered during boot time.
In my case gphoto2 --reset did the trick. Powering the camera off and on didn't help.
