How do I find out? I just plug the camera in.

This "only" gives:
helge@samd:~$ gphoto2 --list-cameras | grep G5
        »Canon PowerShot G5 (PTP mode)«

helge@samd:~$ LC_ALL=C gphoto2 -L --camera "Canon PowerShot G5 (PTP mode)" --port "usb:"

*** Error ***
An error occurred in the io-library ('Bad parameters'): No error description available
*** Error (-2: 'Bad parameters') ***

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 <[email protected]>, please run
gphoto2 as follows:

    env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt -L --camera "Canon PowerShot G5 (PTP mode)" --port usb:

Please make sure there is sufficient quoting around the arguments.

However, I just by chance tried as root:
root@samd:~# LC_ALL=C gphoto2 -L
There is no file in folder '/'.
There is no file in folder '/store_00010001'.
There is no file in folder '/store_00010001/MISC'.
There is no file in folder '/store_80000001'.

Strange, so it must be a permission problem. Also -P works (as root).

Greetings

          Helge
