libgphoto2

Hi,

I reinstalled my linux box (debian/lenny).
Before that I could get the pics from my camera.

Now I get the message:

"""
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.
"""

I can get the pics as root.
I am (as a regular user) in the group of plugdev.
I even created a usb group to have usbfs mounted with this devgid. I am in that group, too.

Based on older threads, I tried to edit
/etc/udev/rules.d/*libgphoto2.rules:
SUBSYSTEM!="usb_device", GOTO="libgphoto2_rules_end"
ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="3138", MODE="0660", GROUP="plugdev"
(Bus 005 Device 010: ID 04a9:3138 Canon, Inc. PowerShot A710 IS)

Still have the same error.

Thanks for your help in advance,
tamas

ok slow down linux sees you camera as a usb hard drive libgphoto program reads this then opens it. so connect your camera push the power then type in a terminal dmesg this will tell you what it is loaded as. then make sure you have disk in your group in user admin. I do not know why this is happening but I just usually plug the camera in open the mounted device the open my pictures. this is not much help but think of your camera as a hard drive that is being opened ok. when I do this it sets my camera device to /dev/sdd1 and then it mounts in in the media folder there also when you do this a icon should show up on your desk top looks like a usb or a camera click it. if none of this is happening then may be a reinstall.

if you have your camera set to webcam this will cause this problem also.

Thanks!
The problem was that usb devices are in group 'virtualbox' and I was not member of the vitualbox group.
