I'm desperately in need of help with building a connection on my Rpi between
My SLRs (Canon EOS 700D and 300D) and Gphoto2. I need to use it as my major
experimental monitoring method. I installed Gphoto2 from apt-get, I can
auto-detect my cameras but can't do any further.
*pi@... ~ $ gphoto2 --auto-detect*

*** Error ***
An error occurred in the io-library ('Could not lock the device'): Camera is
already in use.
*** Error (-60: 'Could not lock the device') ***
For debugging messages, please use the --debug option.
