GThumb fail to import photos from Canon S1 IS

[Łukasz Halman]

My camera is Canon S1 IS. It worked flawlessly in hoary. After upgrade to breezy
it stopped. Gthumb fails to import photos with an error "lock keys failed". I
investigated this issue and it seems the problem is that camera is working in
'normal mode', which is problematic in this case. I works well in 'ptp mode',
which can be forced with 3rd party tools like: gtkam, gphoto, but not gthumb.

Martin could that be a gphoto issue?

[Martin Pitt (pitti)]

Can you please install the "gphoto2" package from universe and try

  gphoto2 --auto-detect

? Does it show two interfaces? Also, please do

 lshal > hal.txt

while the camera is plugged in and on, and attach hal.txt here.

Gphoto --auto-detect shows only 'normal mode'. However I can force 'ptp mode'
and download pictures from camera. There's a bug in gphoto bugzilla about it:

https://sourceforge.net/tracker/?group_id=8874&atid=108874&func=detail&aid=1224783

Perhaps there's a way to force hal/gphoto to use 'ptp mode' by default? Just how
it did in previous versions?

Thanks for looking for the upstream bug.

hal already shows a PTP node for the camera, and since hal does not actually
"do" anything, it can't be forced to anything. However, I can't find a gthumb
command line option for forcing PTP mode, how did you do that? If there was a
switch, I could modify gnome-volume-manager-gthumb to use it if a PTP node is
present.

However hal in some way cooperates with gphoto2 database of cameras as far as I
understand. Right now gphoto2 advertises S1 in both normal and ptp mode. The
first one is automatically chosen. Maybe if it was somehow deleted from the list
of supported cameras it will initialize camera in ptp mode?

I can force ptp in two ways:

1. using gphoto with following command:
gphoto2 --camera "Canon Powershot S1 IS (PTP mode)" --port usb: --additional-options

2. I launch gthumb _before_ camera is connected and I click on "Import Photos".
The camera abviously cannot be found and gthumb allows user to choose camera
manually. I chose S1 in ptp mode and connect camera.

I am having the same trouble with my Powershot S1 IS. This last comment was
helpful to me, but does not seem to work all the time. I import photos before
the camera is attached. Since it cannot find a camera attached it allows me to
choose my camera. After choosing my camera (in PTP mode), it says "No Images
Found". I then plug my camera in. It still says "No Images Found". I click
import and I get a dialogue saying "No Images Found". I have also tried opening
the choose camera dialogue and then plugging my camera in before I actually
choose my camera. I still get "No Images Found". I had this method work once
but cannot figure out what I did differently that time.

I get exxactly the same as above with my Powershot A630. If I plug camera in and select import photos when edgy detects the camera, I get:

An error occurred in the io-library ('Could not claim the USB device'): Could not claim interface 0 (Operation not permitted). Make sure no other program or kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device.

Do you still get the bug on Ubuntu 7.04?

[Lorenzo De Tomasi (lorenzo-detomasi)]

Same problem on Ubuntu 7.04 with Canon Powershot A430 :-(
I'm a newbie, so please give easy instructions :-)
Thanks

[Łukasz Halman (lukasz-halman)]

As far as Canon S1IS is concerned everything works fine in 7.04. Camera works in PTP mode with no problems whatsoever.

[Daniel Holbach (dholbach)]

Does it work for everybody in Feisty or Gutsy?
