Make sure no other program or kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device. ERROR: Could not capture. *** Error (-53: 'Could not claim the USB device') *** 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 <gphoto-devel at lists.sourceforge.net>, please run gphoto2 as follows: env LANG=C gphoto2 --debug --capture-image Please make sure there is sufficient quoting around the arguments. [antwerp at bepstein][~/scratch] Running the debug version essentially yields the same plus lots of step-by-step messages regarding the comms to and from the camera. Boris.
