#520 Unable to retrieve images from HP Photosmart M415
Hello,
I can intermittently get images from this camera. When I
cannot, I get the following:

Hmm. Unclear.
Is this the *first* run after plugging in the camera?
Does the behaviour change when you run "gphoto2" as root?
Logged In: YES
user_id=240921
No, this happens in subsequent runs. The first time it works
fine, afterwards I have this problem. Not sure about the
root thing, I'll check.
Logged In: YES
user_id=48092
the problem will be in the run right before the failing
one, since the above one is not able to connct back
to the camera.
can you post a --debug trace of the call before the failing
call?
(root is no issue, if it works once the permissions are
ok.)

I'm now using Ubuntu Dapper 6.06 LTS.
Gnome recognizes the camera and loads thumbnails of the
pictures. When I select one picture and click the import
button I get an error "PTP Protocol Error, response
expected" The window hangs until I kill it.
Here are what I think are the relevant processes from ps -ef

It appears on the last run that the camera trys to get data
from the camera but then loses that connection part way
through the transfer. That seems to be what I experience
when I attempt to get a picture off the camera, it begins to
transfer but then errors out.
Logged In: YES
user_id=48092
such a trace would be helpful (where it actually loses
the transfer)

The last trace I sent has that behaviour.

I saw the bug today at OLS after being heckled by a fellow
user attending the conference.
Basically ptp_usb_getresp() returns PTP_ERROR_RESP_EXPECTED
ptp.c:258 after downloading the picture.
I don't have the camera but can arrange traces and stuff.
This looks like a bug in the firmware.
After that the camera is in a wrong state and shoudl either
be unplugged or switched off.

traces would help :)

How do I do a trace? If you can provide instructions I'll do my best to do it.
please try libgphoto2 2.4.3, it is likely much improved
