Photo import stopped working with Canon PowerShot A520

[dierre]

Binary package hint: libgphoto2-2

I am no more able to download images from my Canon PowerShot A520 camera.

When I plug in the camera the usual dialog asking if I want to download the images appears.
When I answer that I wish to download them, the dialog the allows to select the thumbnails
appears, but instead of the thumbnails the following appears:

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.

This appears with libgphoto2-2 version 2.3.0-0ubuntu4 -- if I revert to 2.2.1-2ubuntu4 the problem disappears.

From /var/log/messages when the camera is plugged:

It seems the permissions for USB devices are not set properly. I got exactly the same error message here with a PowerShot A70, so I investigated.

After applying the following patch, it worked.

Confirming this regression. The suggested fix is only partially effective. This camera worked fine in Edgy, and was broken by an update at some point, and remains broken in Feisty.

-BUS!="usb*", GOTO="libgphoto2_rules_end"
+SUBSYSTEM!="usb_device", GOTO="libgphoto2_rules_end"

The above change does restore the camera import, but the camera will mysteriously shut itself off during the import after a minute or so, ruining any in-progress import. This did not happen under edgy, where the camera would stay on for the entire import.

I have a Canon Powershot A430 and I have a similar problem: after updating to the last version of ubuntu when I connect the camera the import window appears, but it shows for a long time the icon "No camera found", the "Loading camera drivers from /usr/lib/libgphoto2/2.3.0" is displayed, but it seems crashed (no working feedback). After abut 5 minutes it displays the error message "PTP I/O Error" and the Import button doesn't work.

Thank you

I have the same regression with a Canon Powershot S2 IS.

In my case reverting to 2.2.1-2ubuntu4 doesn't seem to fix the problem: I get the import dialog and then nothing happens.

This sounds like the Auto Power Down feature of the A520. I found I have to disable it to get a full import (even in edgy).
My camera occasionally resets to its default settings, most recently last week, so this is an ongoing problem.

[Marc Guillemot (mguillemot)]

On my laptop import works just fine with libgphoto 2.3.0-0ubuntu4 what means that this library is not the cause of the problem (or at least not alone).

[Thom Pischke (thom-pischke)]

This is now working in Feisty using the suggested fix. Problem was on a friend's computer and he reported that one day everything just started working great.

I can only assume that some update came through, but probably the USB fix was necessary as well, assuming the update didn't overwrite that config file.

[David Hillman (hillman-planet-torque)]

I have a Canon Powershot SD550 that was working beautifully with Edgy Eft. I "upgraded" to Feisty Fawn yesterday, and now the camera is not recognized at all. I applied the patch above, but that failed.

Had I known how many things were going to need to be redone after installing FF, I never would've bothered.

[Marc Guillemot (mguillemot)]

This is now working for me again. I suppose that some update fixed the issue but I can't say which one as I haven't tested again after each update.

[Martin Pitt (pitti)]

Closing again as per Marc's comment.

[Thom Pischke (thom-pischke)]

*Was* a fix released? Don't really remember seeing a gphoto update come through....
