Olympus Camedia C-480 Zoom camera and Digikam 0.9.2-final

[Write Me]

Dear Digikam

I have an Olympus Camedia C-480 Zoom camera which works perfectly with
Digikam 0.8.2 on my Mandriva 2007 machine.

However, I have not managed to get it to work with Digikam 0.9.2-final
on my Kubuntu laptop.  I have tried all the usb sockets on this machine
  but the exact model is not found.  If I select Auto-Detect the camera
detected is an Olympus C-370Z.

Once detected and added to the list, I press Camera > Olympus C-370Z.
However the error message is "Error failed to list files in /".  I
retested on the Mandriva using the same camera and lead and it worked.

As a result of the camera connecting to the laptop a new icon called
"USB MAss Storage Interface", appears on the desktop.
If I click this dolphin opens and reports an error: "Could not read file
  Error writing to the port".

Is it possible to solve this problem.

Thanks and wait to hear

Stephen

I have had a similar experience with an Olympus Stylus 810: please see my post

Ditto.

I have also got this error message although it is not mentioned in my email; two
other error messages were.

Ditto.

There is no camera driver in digiKam. libGphoto2 is used for that.

I have an Olympus Camedia C-460 which works fine if you set it up as a
USB mass storage device.  I have a note to myself which says:-

    * Connect the camera to the USB port
    * Look in /var/log/messages, there should be a new device /dev/sdc1 created
    * As root "mount /dev/sdc1 /mnt/camera"
    * The pictures will then be in /mnt/camera/dcim/100olymp
    * Create a new directory in /two/pictures/downloads and copy the pictures there

Obviously your destination directory won't be /two/pictures/downloads
so you'll have to adjust that for your set-up.  You'll also have to
create /mnt/camera (or whatever you want to call it).

I posted my problem to the gphoto-users mailing list as suggested by Gilles
Caulier. There, I got a useful hint from Marcus Meissner; see:

http://tinyurl.com/2lqda7

for details.

> Is it possible to solve this problem.

This is what I did:

1. I commented out lines like:

ATTRS{idVendor}=="07b4", ATTRS{idProduct}=="0109", MODE="0660", GROUP="plugdev"

in /etc/udev/rules.d/45-libgphoto2.rules

The script below can be used for this:
--------
#!/usr/bin/perl -i.bak -pl
# OlympusModifyUdevRules
# Suggested by Marcus Meissner <[hidden email]>
# on the gphoto-user mailing list
# at http://tinyurl.com/2lqda7
#
# Invoke as
#
# sudo ./OlympusModifyUdevRules /etc/udev/rules.d/45-libgphoto2.rules
#
#
use warnings;
use strict;
m/07b4/ and m/0109/ and s/$_/# $_/;
--------

FYI, the two magic numbers above refer to:

07b4  Olympus Optical Co., Ltd
0109  C-370Z/D-535Z/X-450

and very likely activate sierra mode before USB mass storage can assume
ownership. Removing those lines will likely allow USB mass storage to seize control.

2. Connect camera to PC and select PC mode on camera for connection.

3. You should see two icons on your desktop; at least one of them should work
with DigiKam.

Please let me know if this works for you.
