cant plugin usb camera, udev problem

# head -n 1 45-libgphoto2.rules

# udev rules file for libgphoto2 devices (for udev 0.98 version)

may be udev version mismatch?

libgphoto2 has nothing to do with /dev/sd* , this is USB mass storage mode.

Well, I have the same problem with kernel 2.6.22-14-generic and a Panasonic DMC-FZ7 camera. I'm using Kubuntu 7.10.
I think this bug is connected with https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/155788

I renamed /etc/udev/rules.d/45-libgphoto2.rules to be /etc/udev/rules.d/45-libgphoto2.rules.backup and it now works: kde opens up the new media window and I can access my files.

The problem (being unable to access camera) exists for camera Olympus C-55Z; after the above mentioned operation the camera can be accessed as usb mass storage camera, but not specifically as that particular type of camera.

I am using Kubuntu 7.10 on i686, application - digikam.

From what I have investigated with my Panasonic Lumix DMC-FX30, on kubuntu 8.04 as well as on current debian/testing, this has nothing to do with udev but really seems to be a problem with libgphoto2's PTP handling of some cameras.

In my case, my camera offers 2 interfaces: one usb-mass-storage (seen on the system as /dev/sdX1) and one PTP. Accessing it as a mass-storage device is no problem, but accessing it with PTP protocol doesn't work. The problem is that something (HAL I suspect, but I'm not sure how all this stuff works) "prefers" accessing it with PTP and ignores the mass storage option.

Anyway, here is what "hal-device" reports after I plug my camera on the computer:

Hey all..

Just trying to poll around and see if someone else is having the same issue and if so - has anyone got a fix? I have a workaround but it sux.

Let me break it down for you...

I have an HP Photosmart M425 Digital Camera. When I plug the camera in things run like they are supposed to until I import the photos. I get an error due to permissions issue. I did some digging and found this bug with launchpad...

https://launchpad.net/distros/ubuntu...oto2/+bug/6602

There seems to be something horky in the udev rules or something that's preventing and it's around that check_ptp_camera script that was in Dapper.

Anyway - if someone stumbles across this and wants to know how to fix it...

1. Modify /etc/udev/rules.d/45-libgphoto2 to look like what is in this link: http://librarian.launchpad.net/49341...bgphoto2.rules

2. Add the following check_ptp_camer script to /lib/udev (make it executable): http://librarian.launchpad.net/4933902/check_ptp_camera

If you do that - the problem should go away. This is a hack|workaround but it works.

1. Create the file and add the content he said to by opening a terminal (Applications-->Accessories-->Terminal):

sudo gedit /lib/udev/check_ptp_camera

2. Next we want to change permissions (using a file called chmod) to make it executable. Before we do that, let's take a look at the permissions already there:

ls -l /lib/udev

You will see that your new file has different rwx permissions next to it. It looks a bit cryptic, but it is really quite easy: the first three are the owner, the next three are the group, and the last three is for everyone else. Go look for 'chmod how to' on google and you will find a better explanation. http://catcode.com/teachmod/ explains it rather well.

So now let's do the permission change:

sudo chmod 755 /lib/udev/check_ptp_camera

If you type

ls -l /lib/udev

you will see that your file is like the others in the directory now. Hope this helps.

Got mine fixed by using rko618's fix here in this thread :

This rules file is not shipped with udev

Does it work under supported Ubuntu versions?
