[Pkg-phototools-devel] Bug#608341: [libgphoto2-2] please add support for Canon IXUS 130 (lsusb -v attached)

[Bastian Venthur]

Hi Andreas,

Thanks for your patch, it works. There are two things:

1. With your patch I'm able to access the camera as Canon IXUS 130 in
KDE's filemanager, w/o your patch I'm only able to access it with
gphoto2 (Why?). W/o your patch the camera is also correctly recognized
in KDE's filemanager but I cannot access the images due to some "unknown
device"-like error.

2. The *real* problem was actually that KDE's filemanager and gphoto2
were not able to access the device, there was an error message like:

  ('Could not lock the device'): Camera is already in use.

I didn't really pay attention to this message since it never happened
with my last camera, and I knew I did not mount the camera. Anyways,
after reading a few bugreports someone pointed to this message and said
he solved the problem by killing all gvfs processes. I looked and
noticed that I had rhythmbox open and the camera was already shown there
as a media device (although it was not listed as mounted device via
"mount"). Closing rhythmbox allowed me to access the camera w/o the
above error message.

Do you think it is a bug in libgphoto or rhytmbox or something else?


Cheers,

Bastian
