Running testing on i386: gphoto2 has just started failing with

-------------
gphoto2 -L --camera "Kodak DC3400" --port usb: -f /DCIM/100K3400

...

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

...

------------

when run by an ordinary user, but is ok when run as root. I suspected a
udev problem, but  udevadm monitor did not show any udev events when the 
camera was connected and switched on.

-----------------------------------------
$ dpkg -s gphoto2
Package: gphoto2
Status: install ok installed
Priority: extra
Section: utils
Installed-Size: 992
Maintainer: Debian PhotoTools Maintainers

Architecture: i386
Version: 2.4.5-2

---------------------------------------------
$ dpkg -s udev
Package: udev
Status: install ok installed
Priority: important
Section: admin
Installed-Size: 956
Maintainer: Marco d'Itri <md at linux.it>
Architecture: i386
Version: 0.141-1
----------------------------------------------

This is just a preliminary enquiry to ask if this is a known problem 
about to be fixed, or do I need to dig deeper? I checked earlier for 
bugs against gphoto or udev for this: no hits.

I have debugged and fixed udev problems before, but sufficiently long 
ago that I need to research again how the udev system works. Unless I am 
barking up the wrong tree...

I am not sure when I last ran gphoto2 without problems, but it was at 
most a month ago.
