Package: libgphoto2-2
Severity: important

[I realize that there are already several related bugs. I couldn't figure out
if there was a more appropriate one to add this info to. Please feel free to
merge/re-severitize/etc. as you see fit.]

Sometime in the past few weeks, the permissions on my Nikon D90 stopped being
set correctly (i.e., r/w for group plugdev). (Whether this was before or after
I upgraded from Squeeze to Wheezy, I don't recall unfortunately.)

"gphoto2 --list-files" gives the classic "An error occurred in the io-library
('Could not claim the USB device'): Could not claim interface 0 (Operation not

I see that the camera (vendor 04b0, product 0421) is listed in

Permissions are set as (the camera is device 007):

3 [~]$ ls -l /dev/bus/usb/002/
total 0
crw-rw-r-- 1 root root 189, 128 Mar 19 16:49 001
crw-rw-r-- 1 root root 189, 134 Mar 20 18:43 007

With the following line added to /etc/udev/rules.d/99-LOCAL.rules:

  ATTR{idVendor}=="04b0", ATTR{idProduct}=="0421", MODE="660", GROUP="plugdev"

then permissions are set correctly (camera now device 008):

4 [~]$ ls -l /dev/bus/usb/002/
total 0
crw-rw-r-- 1 root root    189, 128 Mar 19 16:49 001
crw-rw---- 1 root plugdev 189, 135 Mar 20 18:44 008

Happy to test; let me know what I can do.

Thanks for your hard work on Debian!
