Get message: The specified camera ("/org/kde/solid/udev/...") is not supported

[Graeme Hewson]

When I connect my camera and select "Download Photos with digiKam" in the device manager, digiKam issues the message:

The specified camera ("/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:16.2/usb3/3-3/3-3:1.0") is not supported.

I'm using a Canon Digital Ixus 800 IS, but others report the same problem with a Canon EOS 6D (https://forum.kde.org/viewtopic.php?f=255&t=120800) and a Nexus 4 (https://bugs.kde.org/show_bug.cgi?id=335870).

It's possible to import the camera in digiKam and continue normally from there.

digiKam 4.0.0 with Kubuntu 14.04.

When I try to import photos from my Nexus 4 smartphone connected via USB in PTP Digikam gives the error "The specified camera ("/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:14.0/usb3/3-1/3-1:1.0") is not supported"

I'm using Kubuntu 14.04 with the updated KDE and Digikam packages from the Kubuntu team's PPA https://launchpad.net/~kubuntu-ppa

Reproducible: Always

Steps to Reproduce:
1. Plug in the Nexus 4 via USB. Set it to use PTP mode
2. Click KDE Device Notifier icon->Camera->Download Photos with Digikam
Actual Results:
Digikam starts up but gives error "The specified camera ("/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:14.0/usb3/3-1/3-1:1.0") is not supported". Unable to access photos on phone.

Expected Results:
Digikam starts up and shows a listing of all photos available on my phone.

Sound like the problem is relevant of KDE Solid interface.

[Graeme Hewson (ghewson)]

I have the same problem with a Canon Digital Ixus 800 IS.

[Graeme Hewson (ghewson)]

I've opened a bug for Kubuntu at https://bugs.launchpad.net/digikam/+bug/1329726.

[Graeme Hewson (ghewson)]

With all debug output enabled in kdebugdialog and digikam running, when I plug in my camera I get these messages:

I am getting this message when opening Digikam from Device Notifier with my mainstream Canon PowerShot SX200 iS, which has been supported for years. Digikam appears to work fine though.

I am getting this on the same Debian testing install as the one I used 2 months ago, when I didn't get this problem with the same hardware. Meanwhile, Solid was upgraded 4.13.1 to 4.13.3. I can't easily test the previous version.

I use Linux 3.14.12. I migrated from sysvinit to systemd since I last saw things working correctly.

Before noticing this bug, I realized that Device Notifier was showing my camera duplicated, as reported in bug 336523. Either these bugs appeared nearly at the same time, or they are related. Moreover, one of the camera items shown (the first) causes this bug, while the other doesn't.

[SinClaus (tomsk-interface)]

I've the same bug with all my cameras, but all ones successfully autodetected by digikam.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[ender (astrothayne)]

I have the same problem with my Kodak M340.

I can open the camera:/ url with dolphin, gwenview, or konqueror, and can open sub folders, however I can't see any of the photos.

I can however import photos using darktable. But that is inconvenient, and doesn't provide a way to delete photos.

[hamelg (hamelg)]

Same thing here on archlinux :
digikam 4.5.0
libsolid 4.14.3
camera is Canon IXUS 115HS
Camera detection is ok in the kde widget device notifier and import photos works flawlessly with kio camera:/, gphoto2 and gwenview.
Digikam puts this error when trying to detect camera :
digikam(10794)/digikam (core) Digikam::DigikamApp::checkSolidCamera: Solid returns unsupported driver handle for
gphoto2

[Ml-n (ml-n)]

I have the same issue with Debian 8.2 (stable).

What works is to import photos through Import->Cameras->USB PTP Class Camera

Was this ever investigated in more detail?

Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. Please try again with the latest version and submit a new bug to frameworks-solid if your issue persists. Thank you!

[Graeme Hewson (ghewson)]

Problem doesn't occur in recent releases.

[Philippe Cloutier (chealer-gmail)]

This appears to be fixed. I cannot reproduce with the same camera (Canon PowerShot SX200 iS) on Debian 9, using Digikam 5.3.0 and libkf5solid 5.28.0-3.

Thanks for the feedback.
