Fedora 18 and gphoto2

[Wade Hampton]

I am experimenting with gphoto2 and getting nowhere with Fedora 18.
Whenever I run it, I get the following:

gphoto2 -L

*** Error ***
An error occurred in the io-library ('Could not claim the USB
device'): Could not claim interface 0 (Device or resource busy). 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 (-53: 'Could not claim the USB device') ***

I have tried as both root and a user, same result.

Running "gphoto2 -a" works and returns info on the camera, but that is
about the only command that works.

The docs on gphoto2's site are rather out of date, and google did not help....

O/S:  Fedora 18 x86_64 with all updates
         gphoto2-2.5.0-2.fc18.x86_64
         Camera is Canon 50D.

Note, testing on Raspberry Pi is mostly working so for now I am
controlling it via the Pi, not my Fedora desktop.

Thanks,
