Issue with Gphoto with multiple calls to camera

Describe the bug I am using a raspberry pi, with ubuntu in which gphoto is being used. The issue is when calling the camera capture command simultaneously, the gphotos stops communicating with the camera, even if it's visible via lsusb. I am using Sony alpha 6100 ILCE-6100L camera.

Name the camera

Model                          Port                                            
----------------------------------------------------------
USB PTP Class Camera           usb:001,007

libgphoto2 and gphoto2 version

gphoto2 2.5.27

This version of gphoto2 is using the following software versions and options:
gphoto2         2.5.27         gcc, popt(m), exif, cdk, aa, jpeg, readline

To Reproduce

Execute the following bash script multiple times one after the other, and one should encounter that after around 10 to 12 clicks the gphoto2 will not be able to connect to the camera
```
ret=1
timeout=20
reps=1
port=$1
id=$2
```

while [ $ret -gt 0 ] && [ $reps -gt 0 ]; do env LANG=C timeout --signal=9 $timeout gphoto2 --debug --debug-logfile='/tmp/gphoto2log.txt' --trigger-capture --wait-event-and-download=FILEADDED --filename="/home/pi/qocoa-photobox/photos/%Y-%m-%d-%H-%M-%S%f${id}.%C" --port=$port

ret=$?
reps=$(($reps-1))

# Check if the process was killed
if [ $ret -eq 137 ]; then
    echo "Process killed with SIGKILL (signal 9)."
    exit 1  # Exit with an error code for killed process
fi

if [ $ret -gt 0 ]; then
    echo "Repetitions left: $reps"
fi

done


- The error that got raised :
```bash                                                                              
*** Error ***              
PTP Timeout

*** Error ***              
An error occurred in the io-library ('Timeout reading from or writing to the port'): The supplied vendor or product id (0x0,0x0) is not valid.

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 <gphoto-devel@lists.sourceforge.net>, please run
gphoto2 as follows:

    env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt --port usb:001,003 --summary

Please make sure there is sufficient quoting around the arguments

Extra Notes:
- As soon as I plug out the usb of the camera and plug it back in, it starts working as normal again. Maybe the usb state is resetting in the camera or so.
- I am saying camera because, when this error was thrown, unbinding and rebinding the port was tried on pi, however, after rebinding same timeout error was raised from above.
- Another thing is reset of the usb port on the pi, this also didn't help
Few Questions:
- Is there some mechanism, like in gphoto2 when such a time-out error is raised, it asks the camera to reconnect again or resets the camera so that it goes to the same state, as when I plug out the camera usb and plug it back again?
