Hi all,
I've got a CentOS 5.4 box and am trying to use it to control either of the two old cameras we've got, one being Nikon Coolpix 990 and the other Nikon Coolpix 995. Accessing either I get the following message:
*** 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 device. ERROR: Could not capture.
*** Error (-53: 'Could not claim the USB device') ***
Any idea what this could be about?
By the way, about a year ago I did manage to use a Linux machine to control one of these cameras (the 990, I believe).
Is the camera set to the PTP mode? Try running 'tail -f /var/log/messages' while connecting the camera and see how it is being recognized.

Thanks.
Just disconnected and reconnected the camera again, got the following:
------------------------------------------ Mar 26 15:23:51 antwerp kernel: usb 2-1: USB disconnect, address 2 Mar 26 15:23:55 antwerp kernel: usb 2-1: new full speed USB device using uhci_hcd and address 3 Mar 26 15:23:55 antwerp kernel: usb 2-1: configuration #1 chosen from 1 choice ------------------------------------------
Looks like the camera is being recognized at least to some degree:
