gphoto2 error - BostonBay - 06-01-2018
Good morning all.
I have Debian installed on my A64, trimmed down to be headless. It only offers SSH connections with only TTY & SSH access.
It works fine but gphoto2 throws an error when attempting to access my Canon EOS 350d.
gphoto2 --auto-detect re4cognises it:
ken@floki:~$ gphoto2 --auto-detect
Model Port
----------------------------------------------------------
Canon EOS 350D usb:002,003
gphoto2 -L or gphoto2 -l returns an error:
*** Error ***
An error occurred in the io-library ('I/O problem'): No error description available
*** Error (-7: 'I/O problem') ***
I also specified a port using --port and tried --summary. Received the same error.
Last year on a Debian build and AMD X64 machine it worked fine. My Win 10 machine sees the camera just fine. Does anyone have any guidance?
Thanks!

Quick follow-up.
I found a post somewhere that indicates in some cases, in order to run gphoto2, the user must be running with root privileges. So, I ran gphoto2 using sudo and it works mostly. When I say 'mostly', I mean that after entering SHELL mode, then exiting, I receive similar errors from my original post. Resetting the camera clears the error.
So, basically my solution to the problem I asked about is to run gphoto2 using sudo.
