Q: gphoto2 does not find my camera. What shall I do?

A: First try to run "gphoto2 --list-ports" and look whether the ports 
   you want to use are listed.
   Then try to run "gphoto2 --auto-detect" and look whether the camera
   is detected.
   If you gphoto2 cannot access the USB device, you have to set up
   hotplugging correctly. See gphoto2.txt for details.

Q: I get the error message

   *** Error ('Could not claim the USB device') ***

   other program or kernel module (i.e. dc2xx) is using the device and
   you have read/write access to the device. 

   What can I do to make it work?

A: You have to set up the permissions on your USB device correctly.
   For Linux, this is described in the file named gphoto2.txt in
   your gphoto2 documentation directory (named doc/ in the source tree).
