#750 Kodak DC5000 hangs on listing files with gphoto2 -L

[Stefan B.]

gphoto used to work fine with my Kodak DC5000 some time ago, but now after upgrading to 2.4.1 or 2.4.2 the following problem occurs:

# the camera is found without problems:
gphoto2 --auto-detect
Kodak DC5000 usb:

# it is possible to get count of files or list directories with
gphoto2 -n
gphoto2 -l

# BUT when listing files with
gphoto2 -L

# at first everything works as it should and the files are listed

# BUT AFTER THAT no more communication with the camera is possible
# gphoto2 -n, gphoto2 -l, gphoto2 -L all hang

Seems as if the camera is left in a unclean state.

Attached debug logs of the following session (in that order):
gphoto2 --debug-logfile=gphoto2-n --debug -n
gphoto2 --debug-logfile=gphoto2-l --debug -l
(working fine so far)
gphoto2 --debug-logfile=gphoto2-L --debug -L
gphoto2 --debug-logfile=gphoto2-L2 --debug -L
(hangs)

Same problem both with 2.4.1 and 2.4.2.

When running a KDE Session kio_kamera also hangs right after plugging the camera in - probably due to the same problem...

might be something for Hub if he still has his camera ;)

I have access to two Kodaks that are absolutely awful to try and get photos off of. Both are rather cheap low end camera's so I always figured that it was the camera. I notice this camera is in the same low end class as the two camera's I have access to. Related? I think so.

Not all Kodak are equal. I have a DC240 that actually use the same protocol as the DC5000 so I can see what is going on. I might even have the documentation for the protocol somewhere.

I did some more testing and the problem seems to occur since version 2.4.0.

With 2.3.1 it workes fine (see debug output in gphoto-2.3.1-L).

gphoto2 --debug-logfile=gphoto2--2.3.1-L --debug -L (version 2.3.1 of libgphoto) WORKED fine
