PTP import

[Tony Bazeley]

I'm a bit new to digikam, and having trouble with import procedures.
Am trying to import from a Huawei P9 phone, configured to PTP mode.

Trying to import using the generic USB PTP Class camera or the digikam suggested option "Huawei P9 Plus" both yield the same error:
"Failed to connect to the camera. Please make sure it is connected properly and turned on."

I'm using digikam-5.8.0-01-x86-64 under Ubuntu 16.04.3 LTS

Would very much appreciate any thoughts on how to proceed.

TIA

Well, the PTP protocol is implement through Gphoto2 driver. If this kind of error appear, this can be a dysfunction located in Gphoto2 driver.

To have more details about, run the appimage from a console and look debug trace printed while you try to read the phone contents.

There's always "Plan B":d/l the images to the machine directly and then let digiKam handle them from there. Sure, it's an extra step or two. Given the current problem, though, it may be the easiest way to fix the problem. :)

I had a similar problem with an iPhone.  I got it to work by fiddling around some.  See http://digikam.1695700.n4.nabble.com/Import-from-iPhone-5-behaves-strangely-td4704878.html

I use an iphone 7 here. I need to grant computer on phone to be able to see items in import tool, else nothing appear. That all. After all, it's Apple security stage, as usual...

Output on attempting to import is below - I'm assuming the ALSA errors are not related

But outside the appimage I can access the Huawei device

tonbaz@muscat:~$ gphoto2 --auto-detect
Model                          Port                                           
----------------------------------------------------------
USB PTP Class Camera           usb:001,011    

tonbaz@muscat:~$ lsusb
.....
Bus 001 Device 011: ID 12d1:107e Huawei Technologies Co., Ltd.

I'm not that familiar with appimage, but understand it to contain all the libraries required.
If that's the case it appears that the problem  lies in the digikam appimage or it's interface with Ubuntu.

As Richard suggests I can transfer files to a Ubuntu directory and import from that directory as a work around.

Should I report this as a digikam bug, or is Is there something else I can do?
