Canon digital camera not showing any more

English Hardware

Hi,

I have a Canon S95 digital camera that used to work just fine. I plugged it in, the device notifier showed a couple of actions for it, I chose digiKam and downloaded the photos.

Now I tried to get new photos out of the device, but it’s not showing in the device notifier any more. DigiKam shows “Canon Inc. Canon Digital Camera (auto-detected)” but doesn’t do anything when selecting it. In dmesg I see

988.197025] usb 1-3: new high speed USB device using ehci_hcd and address 4
988.313730] usb 1-3: New USB device found, idVendor=04a9, idProduct=3212
988.313734] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
988.313738] usb 1-3: Product: Canon Digital Camera
988.313741] usb 1-3: Manufacturer: Canon Inc.
988.313743] usb 1-3: SerialNumber: [number]

So it works but KDE doesn’t seem to be able to notice it. Any ideas what could be wrong?

I’m using openSuse 11.3 with KDE 4.6 RC1, and it might be that 4.6 betas/rc broke the functionality though I’m not sure. Do tell me if I should take this question to the KDE forums instead.

I would try deleting all the digikam config files in your hidden files section

Check for the folder in .kde4/share/apps

and config files in: .kde4/share/config

Removing the digiKam config file did nothing. Neither would I expect it to do – the problem is that the camera is not shown even in the device notifier that lets me choose what to do with the device. I would expect the fault to be in whichever part of KDE is responsible to deal with external devices.

The camera is shown in Yast hardware information, and now it shows also in System Settings > Digital Camera (as “USB PTP Class Camera”).

I went back to digiKam and selected Import > Cameras > Add Camera Manually… and chose “Auto-Detect”. This added a similar device (“USB PTP Class Camera”) to digiKam’s device list. DigiKam is able to operate on this, and I finally can resume to download the pics from my camera.

It’s still not visible in the Device Notifier, but I’m just happy to be able to use the camera again.

That’s using the camera’s PTP protocol (with libgphoto2 support).

You would also like KDE4 to recognise the camera as a usb storage device, so that it can be mounted.

I guess that’s how it used to work, and sure, that would be the optimal situation. However, I think I’ll be happy with the current functionality – there’s quite enough things to tweak and fix anyway. Thank you for the pointer to the solution though!
