Camera Canon Ixus 30 USB FC8

[Basilicum]

FC8, running root

Physically connect Canon Ixus 30
Camera import GUI pops up
Click Import Photos
Dialog: No camera detected
After a few sec's
Canon Digital Ixus 30 (normal mode)
Message: "Camera not ready, multiple 'Identify camera' requests failed: OS error in camera communication"


Searched the forum, found following:
i too have this problem with a Canon A460 ... looks a recurrence of something previous I had in FC5

edit 50-udev.rules

find the lines as follws and change mode 0644 to 0666.

SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \
NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644"

ACTION=="add", SUBSYSTEM=="usb_device", \
PROGRAM="/bin/sh -c 'K=%k; K=$${K#usbdev}; printf bus/usb/%%03i/%%03i $${K%%%%.*} $${K#*.}'", \
NAME="%c", MODE="0644"

This is problably a kludge (I dont know for sure what impact this would have), but it lets my camera work for now.

I did not find a file 50-udev.rules. I found a file 50-udev-default.rules. I looked for the two places with 0644. I found only one.
Changed that, no effect.
But I do not know how this udev mechanism works, the editor left a backup of the original file, so maybe that is another problem.

Suggestions ?

Got the same problem. Anybody have resolution?

I got the advice from several forums to register a bug.

https://bugzilla.redhat.com/show_bug.cgi?id=387251

Perhaps it helps developers as you describe your problem such that they can reproduce,

[piotreek]

I already subbmited bug. https://bugzilla.redhat.com/show_bug.cgi?id=426869

Got the same problem with a Canon PowerShot A640. It worked perfectly with FC6. I tried the 0644 -> 0666 trick, only to get the message:
"DBus error
org.freedesktop.DBus.Error.ServiceUnknown:
The name :1.1605 was not provided by any .service files.
Please select another viewer and try again."

Anyone with a solution?

Thanks

I also have this problem but with an IXUS 500:

The error I get is:

I had no problems importing photos with FC7, in FC8 it would work only if I waited long enough before clicking to start importing, but on FC9 it completely stopped working. I also tried changing the permissions in 50-udev.rules but that had no effect.
