Bug on using Canon EOS 350 D import feature from gphoto

[Alexander Domanski]

When plugging in the Camera a popup shows as wanted and asks wether to download the pictures on the camera. If you select »Delete downloaded files« (a checkbox, I translated this back to english from German, so the text might be something else), after downloading all the stuff to the given place the programme tries to delete the stuff. This produces a read error. The programme calls this »Error 0x0002«. It is not a very important bug as all files are downloaded correctly but not deleted, but it simply sucks to be forced to use the cameras formatting function.

[Ante Karamatić (ivoks)]

But, it opens gthumb2, not gphoto2 or gtkam. And I can't reproduce this with EOS 300D.

[Alexander Domanski (alexander-domanski)]

Sure, but what do you think does gthumb use as the »backend«? Well that's libgphoto2 and gthumb prints this error of libgphoto2 in the progress bar on the bottom of the »sync window«. I have had different kinds of trouble with the 350 D on Hoary and SuSE 9.x but now it at leasts works to upload stuff without using a card reader. About the 300 D, I guess this model should have been working on Linux for more than a year from now, so it is clear why you don't get this error. I guess this is because the 300 D uses another processor (Digic-I?) than the 350 D (Digic-II) but I can't ensure this is the cause.

[Martin Pitt (pitti)]

Can you please install the "gphoto2" package from universe and (try to) remove all the pictures on the camera with

  gphoto2 --debug -D 2> gphoto-delete-all.log

Please attach gphoto-delete-all.log here.

[Alexander Domanski (alexander-domanski)]

I'd love to do so Martin but my Notebook is being repaired so I don't currently have a PC running Ubuntu available.

[Alexander Domanski (alexander-domanski)]

Okay, I finally got my old Notebook running Breezy:

I also have a Canon 350D and can confirm this behaviour both under breezy and dapper.

I get a "ptp: ... reading event ... 0x2002 ... error", but my photos are correctly downloaded and deleted, but it takes a rather long time to delete the photos.

[Martin Pitt (pitti)]

Hubert, do you have an idea about this?

[Marcus Meissner (meissner)]

This is a bug in the PTP2 driver of libgphoto2.

I have fixed it _after_ the 2.1.99 release, so it will only be available then.

svn diff -r8520:8521

is the patch

[Hubert Figuiere (hub)]

Attached is the patch to fix the bug taken from the SVN as mentionned by Marcus. I'm not sure it will apply cleanly as some lines in the camera list may not be in 2.1.6. If you need help integrating in the current package, let me know.

[Martin Pitt (pitti)]

 libgphoto2 (2.1.6-5.2ubuntu7) dapper; urgency=low
 .
   * Applied upstream patch to fix delete command handling of some Canon
     cameras. Also added a few more Canon Vendor/Product IDs. Thanks to Marcus
     Meissner and Hubert Figuiere! Closes: LP#2767

[Hubert Figuiere (hub)]

patch is in upstream 2.2.0 and later. closing that one.
