Can not connect camera in PTP mode using 2.6.23.1-10

[lone73]

My Kodak works now. Much obliged. Seems like it works a little differently than before, it gives a momentary note that the camera is not detected until it loads drivers. Don't remember it doing that before but at least I can upload my photos.
thanks for the info

My brand new PTP Kodak MD853 gives the same io-library error in FC7. I tried it on FC8 and it works fine. The permissions for 50-udev-default.rules (FC8s version of FC7s 50-udev.rules) did not have to be modified. The file is organized differently but it still has 644 for usb permissions. If anyone can explain this don't be shy.

For those of you where changing udev.rules did not have the desired result, read on....

I have a Canon Powershot A80 camera that worked perfectly in Fedora 7 with kernel 2.6.21-1.
However, after yum update, starting with kernel 2.6.23.1-10, I got the same connection-problems as poster.
Changing udev.rules did not have the desired result, but I found the solution here :
http://www.hyperborea.org/journal/ar...m-permissions/

So the command I used (as root) was this:

/usr/lib/libgphoto2/print-camera-list udev-rules-0.98 group users mode 0660 > /etc/udev/rules.d/90-libgphoto2.rules

Note that where it says “users” you should substitute the name of the group your account belongs to.
(In Fedora, that might actually be the same name as your username, since it likes to create a group just for you.)

Now my Canon Powershot A80 camera works perfectly again, running Fedora 7 with kernel 2.6.23.8-34 !

Thanks Biodomo!

I had the same fault with a FinePix F40 after updating Fedora 7 to kernel 2.6.23.8-34. Looked for 50-udev.rules and it had disappeared!

/usr/lib/libgphoto2/print-camera-list udev-rules-0.98 group users mode 0660 > /etc/udev/rules.d/90-libgphoto2.rules

works perfectly.

I saw the advice and changed the usb permissions from 0644 top 0666 and it worked. Unfortunately the next update changed the format of that file to the one that's in FC8 and the camera stopped working. SO I went again and fixed the permissions and it worked. This is obviously a bug. It should either work with 0644 or it should be 0666.

Drat. I just tried the edits on my parents computer (F8). Their Canon G9 won't connects, but gives the error in the import photos application.

Is this a recognised issue? Is a fix imminent?

Cheers & Merry Christmas

I have the same problems with Fedora 8 and a Fuji Finepix, which used to work perfectly. I tried Wayne's fix and it did work BUT the next time I booted up there was a string of error messages flashing by. Despite this, Fedora started, apparently ok, but when I started Firefox I got a message warning about security settings and I could not connect to a secure site. So I put the 50-udev-default.rules file back the way it was and next time things seemed to be normal - until I noticed that the cd driv e was no longer recognised! I am guessing that something has been corrupted but I have no idea what. I suppose I will have to reinstall Fedora.

So my conclusion is: edit 50-udev-default.rules, if you must, but put it back the way it was before rebooting.

you're lucky that your cameras ar detected at all... i my camera isn't functionig at all on fedora8 (on win it worked fine) a have a d-max camera o an asmobile z96s barebone laptop

Further news... reinstalled Fedora 8 and it detected the camera and uploaded pictures fine, both before and after updating. Then I put back my /home folder as it was and the camera link stopped working. So it's not Fedora as such, but something in the user's home folder. Trial and error showed that two hidden folders both cause a problem, .sane and .gcjwebplugin. Move these somewhere else and the problem goes away.
