[antwerp at bepstein][~/scratch] gphoto2 --capture-image

*** Error ***
An error occurred in the io-library ('Could not claim the USB
device'): Could not claim interface 0 (Operation not permitted). 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
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.

Running the debug version essentially yields the same plus lots of
step-by-step messages regarding the comms to and from the camera.
