error with USB cameras and PTP mode

[hauke]

Since upgrading to Ubuntu 8.10 my camera has a permission problem. When pluging the camera cabel into my computer an error messege appears like:

CANON Inc Digital Ixus 55 (PTP mode)/Powershot SD450 (PTP mode couldn`t be mounted. Error initializing camera: -60: couldn`t reserve the camera alone (sorry for my bad german-english translation).

The camera works fine under 7.10 & 8.04
I found some other users in the german support forum with the same problem.
This is a (incomplete?) list of cameras wich doesn`t work anymore:

canon ixus 55
Caplilo G3
HP PhotoSmart 720
Nikon 4200
Fuhitsu F31/fd
canon ixus 850
canon ixus 75 (maybe all ixus types)
panasonic cameras

I have got the same problem with my Logitech ClickSmart 310. The error message is nearly the same.

Now in Nautilus' sidebar the camera appears twice. One is mounted, the other isn't. And when I open 'computer:///' the camera appears three times, but also only one is mounted. (--> screenshot in attachment)

In /dev/ is no file 'video' or 'video0'.

The same problem here with an IXUS 55 and an IXUS 850.

I have the same problem with my HP Photosmart 635, which is just a USB mass storage device. I notice that in the older versions in which it worked, it would appear as a /dev/sdXX (e.g. /dev/sdb and /dev/sdb1) device. In Ubuntu 8.10, it doesn't, and instead appears as /dev/usb-<something> or something like that. But attempts to mount that device fail. The camera itself claims to be connected to the computer though.

It's not a bugfix but a possibility to avoid the bug and get the pictures from your camera:

1. start "gconf-editor" (via console)
2. go to "/ → apps → nautilus → preferences" and remove the checkmark for "media_automount"

[Adam (richard-adam)]

Yes, that does avoid the problem; thanks. So it's a bug in Nautilus / Gnome automounting I guess?

[Koset Surakomol (koset)]

The workaround worked for me. Thanks!

[Maxcel (dave-maxcel-deactivatedaccount-deactivatedaccount)]

The media_automount did not work for me, but the following did, without changing the media-automount setting.

On the camera go to Menu -> Setup Menu -> USB and change the USB Configuration from 'Disk Drive' to 'Digital Camera'.

My particular model is a HP Photosmart R507, but it throws the same error in Disk Drive mode. The actual menu navigation on individual cameras may be different, but it may be worth trying.

The same Problem for me since the updating process from Hardy to Intrepid, but i use an Logitech Quickcam. No connections in MSN or in Skype. Its boring. And MSN uses an adress ive never heard about.

I also had an issue with improper mounting of my Nikon CoolPix 4600. Similar to what Maxcel did above with his camera, on the camera, I went to Set Up -> Interface and changed the USB option to PTP instead of Mass Storage. It automounts fine now and I can access my pictures without a problem.

[joyfm (ih-mon)]

It's annoying that this problem is still not fixed. It seems it has something to do with cameras which support PTP (Photo Transport Protocol) AND registering as a mass storage device. I think there was in 2005 some disscussion on the gnome-volumemanger maillinglist.

...but for the bug report - same problem here with Kodak Easyshare Z8612 IS under Ubuntu 9.04

Hi hauke,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/karmic . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 297594

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
