Only root can download pictures from USB camera with GPhoto2

[JanErik]

After I upgraded some packages, perhaps most significant the 2.6.12-gentoo-r4 kernel, only root can access my camera with GPhoto2.

As a normal user I get

I had the exact same problem recently and posted about it, and another user gave me the solution.

See the thread here.

Actually, what has changed that doesn't allow a regular user to access USB cameras?

[Sadako]

I'm not certain, but odds are it came with either the recent baselayout or udev updates, probably the latter.

Had the same problem but, like the dork I am, forgot to check my groups.

#gpasswd -a username usb

did the trick.

My problem was with accessing my dvdrw drive after a kernel upgrade so I obviously used a different command sequence but you get the gist.

Hi,

I faced exactly the same problem due to a switch of kernel where I also moved to udev. You may access your camera in two way, mass storage or PTP (some cameras do not provide the choice). Fixing the problem is quite different depending on the acces method:

- Mass storage. You basically see the camera as device (something like /dev/sdx) that you mount as a standard mount. In case of permisision problem hear, check the udev rules and make sur your user belong to the appropriate group

- PTP. In this case, libgphoto accesses the camera directly without mounting it anywhere. I prefer this method since you can also control the camera using gphoto2. In this case I fixed it my replacing the usbcam script that sets the permissions to the console owner with the usbcam.group script and assigned my user to the camera group (as described in http://www.gphoto.org/doc/manual/permissions-usb.html)

Hope it helps,

Tom
