How to (auto-) mount a usb camera with user permissions on Raspian Pixel and gphoto2? -


i connecting canon dslr using gphoto2 on raspbian pixel. gphoto2 runs if run commands using sudo. example:

 user@machine:~ $ gphoto2 --summary   *** error ***                error occurred in io-library ('could not claim usb device'):   not claim interface 0 (operation not permitted). make sure no other  program (gvfs-gphoto2-volume-monitor) or kernel module (such sdc2xx,  stv680, spca50x) using device , have read/write access  device.  *** error (-53: 'could not claim usb device') ***         debugging messages, please use --debug option.  debugging messages may finding solution problem.  if intend send error or debug messages gphoto  developer mailing list <gphoto-devel@lists.sourceforge.net>, please run  gphoto2 follows:  env lang=c gphoto2 --debug --debug-logfile=my-logfile.txt --summary  please make sure there sufficient quoting around arguments.

whereas, using sudo, fine:

 user@machine:~ $ sudo gphoto2 --summary   detected 'canon:eos 350d (normal mode)'  camera summary:   camera identification:    model: canon:eos 350d (normal mode)    owner: unknown   power status: on battery (power ok)   flash disk information:    drive a:      1,975,680 bytes total      1,915,360 bytes available   time: 2017-04-07 11:51:19 (host time +0 seconds)

i trying incorporate camera control python program, sudo won't option down road. assuming it's matter of setting read/write permissions camera when it's mounted. how can determine path camera , set permissions user account has proper access every time it's connected won't have use sudo?
