[gphoto-devel] Capture error - EOS 5Dsr

[Daniel Muller, jednatel SourcePaint s.r.o.]

Hi everybody including Marcus,
I have issues using ligphoto2 with this Canon 5DSR ..
It very often loses connection or part of commuication while doing various
things..

Attached, is a log of one of them during the capture image..
I have no idea, how to fix this kind of issue. I was thinking maybe it is
in libusb..

I am running 4.2.0-35-generic #40-Ubuntu SMP Tue Mar 15 22:15:45 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux

I have built (lib)gphoto 2.5.10 ..
the libusb packages hat i have (or don't) - if the information is useful
anyhow..

ii libusb-0.1-4:amd64
2:0.1.12-27 amd64 userspace USB
programming library
ii libusb-1.0-0:amd64

1.0.9-1build1 amd64 USB multiplexor

Any ideas what it is?
Any ideas how to get more relevant info?
Any ideas what to try?

Thanks

Daniel

you are still using libgphoto2 2.5.8 though ...

The busy at the end signals we had a hickup during capture, like loss of focus
or something.

2.5.9 and 2.5.10 improve on the capture method for the newer EOS cameras, so it
is worth trying them.

Ciao, Marcus

Allright, sorry, I have not noticed that 2.5.8 is still in use..
F**k, the whole ubuntu depends on the on old version..
Let's try to set LD_LIBRARY_PATH CAMLIBS and IOLIBS..
It seems like 2.5.10 now. I cropped the log before the downloading..
Just to note, those communication errors seem not to be specific to
capture, though, they often happen during capture..
I hope this log would show, where is the issue..

Thanks and sorry for the previous useless log..

And that hangs for 20 seconds.

Hard to say.

Can you try attached patch?
