Description Unknown 2007-06-18 10:34:21 UTC

Version:           0.9.1 (using KDE KDE 3.5.7)
Installed from:    SuSE RPMs
OS:                Linux

Using my Canon EOS 350D in PTP mode I got the following problem:

The camera is recognized, but if digikam tries to connect to the camera for downloading the pictures, an error occurs, that digikam can't connect to camera.

If I use gphoto2 directly from console, there ist no problem, all pictures are listed correctly. After initializing the camera from console using gphoto2 -l or gphoto -L, digikam is also able to connect and lists the pictures correctly.

This is very confusing, it seems to me, that something during the initialization procedure of the camera fails, if digikam has to initialize the camera. If the camera is initialized, everything works fine.

Installed libgphoto2 is 2.2.1.5.trunk-22@i586.

Have you tried using the "Canon EOS 350D" entry in digikam, i.e. the one without PTP? I know it seems weird, but if I recall correctly, I had to drive my 350D in PTP mode with the entry that didn't have PTP in it.

I just tried to connect the camera with and without PTP mode. In both cases digikam can't establish a connection to the camera. After initialization with gphoto2 -L digikam works fine again.

Additionally I have to say: the connection with the camera worked fine for a long time. The problems occured after an online update last week, where the digikam packages were upgraded. Unfortunately I can't say in detail, which libraries have bee upgraded by this update.

Achim,

PTP camera transfert is supported using GPhoto2. digiKam do not implemente PTP protocol.

I suppose than you have updated libgphoto2 package too.

It's certainly a bug in libgphoto2. Perhpas this one have been fixed with last stable release of the library. Try to update and test again...

Arnd, i suspect this bug is fully relevant of libghoto2.

Achim,

Can you update libgpghoto2 on your computer and try again. Thanks in advance

Hi Gilles,

I updated my libgphoto2 and what should I say: it works. Thanks for that hint.
