I'm having problem with one device, a Nikon D90 camera, that won't automount. At some point in the past, I had set something that would cause it to be detected, but the only option offered was to download pictures with Digikam. (At some time in the past, the device notifier would offer options including opening the device in Dolphin which is what I'd prefer.) For some reason, this function didn't work properly because Digikam would open and stall on the process of detecting my images, and never would open. I have a very large image archive and this process could take a couple of minutes in the past, but it would eventually open. This camera will mount under Windows; however, in Windows, the icon never appears that allows you to eject it gracefully once you're ready to dismount it. When I attach the camera to the Windows box, it automatically opens an explorer window and shows me the folder structure, but, the eject button never appears.
What I've done: I've gone into the device notifier widget settings and tried finding there, a way to disable the mount with Digikam option, but could find nothing there that affected the behavior I've removed the device notifier widget and re-installed it - no difference I found the auto-mount files "device-automounter-kcmrc" and "kded-device-automounterrc" and renamed them and restarted KDE - no difference I removed Digikam (I really don't want to use this app anyway, as I find it cumbersome) - now, the device notifier doesn't ever show the camera I re-formatted the memory card in the camera Lots of google searches on this issue, but haven't found anything else that helped Tried my other camera, a Fuji 9000, and several pen drives - these all automount successfully and offer various options for how to mount the devices with various applications
The strange behavior under Windows (it automatically opens a folder with the camera memory card's root folder displayed, BUT, never produces the eject icon) makes me suspect this is some issue with the camera, but, what could it be?
No one responded on this query, but, for the sake of posterity, here's the fix: Many modern digital cameras have two modes in which the flash memory operates, USB and PTP; I do not know what PTP means, but the effect of it is, it doesn't allow the memory to be seen as ordinary flash memory. Digikam can recognize a connected device operating in PTP mode and that's why it worked there. In Windows-land, PTP mode, as I understand it, is designed to work with Nikon's own software for managing photos. I do not know if other manufacturers use this protocol, or whether it's unique to Nikon. On some Nikon cameras, there are options in the menu to run the memory in USB or PTP mode, but, the D90 does not offer this choice, and can only run in PTP. The fix is to either use Digikam or other software that can work with PTP mode enabled memory, or, remove the memory from the camera and use a card reader.

I believe it means "Push-to-Print", permitting you to print photos directly from the camera to a PTP-capable printer. The camera retains control of the memory in that mode as opposed to becoming a USB memory card reader in the "USB" mode. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@nerd.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - We are born naked, wet and hungry.

minor point, but, PTP may also be known as...

my recollection was a peer to peer definition, also wrong. :-)

And I think you're right, that sounds much more likely than my name, but the concept is identical.

Yes, and (being the car racing nerd I am) it can also mean "push to pass" as used in Indycar racing's time-limited turbo boost button.
Ah, acronyms. Remember when ATM meant "asynchronous transfer mode" as used in networking and not "automated teller machine" as in "I need $20 NOW!"

and thanks for that link - Rick was pretty close but that nailed it down

that makes perfect sense and coheres with my experience - thanks, Rick

I use Digikam with my Nilon D60, works great. I just used it TODAY with my older Olympus C-750Z zoom.. I had taken some videos of the hummingbirds outside.. Digikam was able to setup and recognize the Olympus, see the files, and transfer them. It was NOT able to delete them, like I can with the Nikon.. Only problem is the videos are .WMV files, that sucks.
