3.1.4.

Why do I get the error message "Could not claim the USB device"?

The exact message looks like

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

Could not claim interface 0 (Operation not permitted). Make sure no
other program or kernel module (e.g. dc2xx or stv680) is using the 
device and you have read/write access to the device. 
      

You have to make sure that no such kernel module is loaded and that you
have set up the permissions on your USB device correctly, such that you
have (non-root) write access to the camera device. How to set this up,
is described at Section 4.3.

the camera yet, so I won't say definitively yet :)
