[xubuntu-users] USB camera being intercepted?

When I run Digikam and plug in my ancient Kodak EZ200 digital camera, I 
see this (using tail -f /var/log/syslog):

> Nov 17 14:50:34 ccepub196 kernel: [16923.417662] usb 7-2: usbfs: interface 0 claimed by usbfs while 'gvfs-gphoto2-vo' sets config #0
> Nov 17 14:50:34 ccepub196 org.gtk.Private.GPhoto2VolumeMonitor[1935]: (process:2894): GVFS-GPhoto2-WARNING **: device (null) has no BUSNUM property, ignoring

Digikam then recognises the camera, but cannot download images from it 
because it says "Cannot connect to camera".

Do I understand rightly from "interface 0 claimed by usbfs" that some 
other process has intercepted the act of the camera being plugged in, so 
that Digikam cannot access it? If so, how do I force Digikam to break 
that lock and claim the interface?
