[Bug 178011] New: Problems of the camera gui with Canon EOS 350D

http://bugs.kde.org/show_bug.cgi?id=178011

           Summary: Problems of the camera gui with Canon EOS 350D
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

i have a Canon EOS 350D. If i connect the camera as USB (the camera call it "pc
connection") it behaves differently from connecting it as Print/PTP mode.

When in USB mode:
Download of thumbnails is really fast.
errors on inverting the downloaded status of a pict. in fact it doesn't work.
deleting of file gives errors, but works.
Capture makes my camera shot repeatedly. But works. To see thumbs of auto-taken
picts i had to restart the camera gui.
In digikam (Import -> Camera (Auto Add)) the camera is called "USB Vendor
Specific..." Adding manually have the correct name.

when in PTP mode:
Download of thumbs is slow. ~30 secs to show thumbs, no matter if there are 3
or 15 photoes.
errors on inverting the downloaded status of a pict. in fact it doesn't work.
deleting of files works, upload of a file does not.
Capture is not available
In digikam (Import -> Camera (Auto Add)) the camera is called "USB imaging
interface" Adding manually have the correct name.

Here is how linux sees the Camera:

usb connection
usb 2-8: new high speed USB device using ehci_hcd and address 11
usb 2-8: configuration #1 chosen from 1 choice
usb 2-8: New USB device found, idVendor=04a9, idProduct=30ee
usb 2-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 2-8: Product: Canon Digital Camera
usb 2-8: Manufacturer: Canon Inc.

ptp
usb 2-8: new high speed USB device using ehci_hcd and address 10
usb 2-8: configuration #1 chosen from 1 choice
usb 2-8: New USB device found, idVendor=04a9, idProduct=30ef
usb 2-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 2-8: Product: Canon Digital Camera
usb 2-8: Manufacturer: Canon Inc.
usb 2-8: USB disconnect, address 10 connection - slower but can delete pictures
from camera

tell me if i have to file a bug for every problem i listed here!

Do you use digiKam 0.10.0 (KDE4) or 0.9.5 (KDE3) ?

gphoto2-config --version  now says libgphoto2 2.4.3

Import -> Camera (Autodetected) -> still says "USB Imaging Interface"

Camera GUI still takes ~30 seconds to generate thumbs of few images

Upload does not work

Deleting files is problematic. Some are deletet immediately, some are deleted
but give errors, some are not deleted at all! (can provide gdb backtrace if
necessary).

toggle the lock status does not work

the PTP mode has occasionaly delete problems. In Normal mode they might not be
there.

The gphoto startup time currently very much depends on how many images you have
on there.

That's not my case. I tried with both 2/3 and ~20 images...

In normal mode it behaves as i wrote in the description above (Revision:
898605)

Gilles, this so-called USB / PC mode is still not USB mass storage, is a
special gphoto2 driver?

Salvatore,
> errors on inverting the downloaded status of a pict
what do you mean by "inverting"? That it gets assigned the check mark sign of
successful download? Which errors?

> deleting of file gives errors, but works.
Which errors?

> In digikam (Import -> Camera (Auto Add)) the camera is called "USB Vendor
> Specific..." Adding manually have the correct name.

Can you give me the output of "solid-hardware list details" while the camera is
connected? We retrieve the camera name from Solid hardware info.

The Canon EOS series does not support mass storage.

The two modes are: "normal" mode, in this you can remote control the EOS 350D
(gphoto2 driver "canon"), and "PTP" mode (gphoto2 driver "ptp2").

Both use different access methods to the filesystem of the camera.

Marcel,

>Gilles, this so-called USB / PC mode is still not USB mass storage, is a special >gphoto2 driver?

It can be. there is a gphoto2 wrapper aroud USB Mass Storage camera. But i
don't recommend to use it. Use digiKam USB Mass Storage interface.

Salvatore,

Please go to Device/Information dialog from menu of Camera Interface window and
look which camera driver you use...

when in PTP mode: "PTP2 driver (c) 2001-2005 by Mariusz Woloszyn . (c)
2003-2007 by Marcus Meissner ."

whe in USB mode: "Canon PowerShot series driver by Wolfgang G.
Reissnegger[...]"

Are those informations correct?

Le me know if you need more!

Another thing (typo?) is that the Camera Interface's window title shows "&USB
vendor Specific Interface"!

SVN commit 900342 by mwiesweg:

Add special handling for Canon cameras for finding out the best label in the
Import menu.
I had put a message on the MLs, and so far received feedback only for Canons.
As I dont have a Canon camera I cannot test this.

Not working for my EOS 350D. Import -> Cameras (Auto-detected) is still showing
"USB Vendor specific interface" or "USB Imaging Interface" respectively if you
are using USB mode or PTP mode.

digiKam revision is 900430

If you need something helpful to find out with this problem le me know

That worked! My camera is now correctly identified by digikam in both USB and
PTP mode, Marcel Wiesweg is my hero of the day!

But still:
USB thumbs on camera gui are fast
PTP thumbs come after ~30 secnods

Should i file another bug or it is gphoto2 stuff?
I'setting this as fixed meanwhile
