My Kodak Z740 is not working

did you check if you have read/write permission on the device file?

how do i do that
cause it was working before like acouple days ago and i didn't mess with anything like that

Hello Reddan1988,
have you a memory card normally plugged in and now you have tried to connect your camera with unplugged memory card? My camera can only successful connect with the memory card plugged in and the card must be formatted or there must be at least one picture. Perhaps you have the same problem like me.

Your question: How do I do that...: I think you should always have read/write access on a usb device automatically. And you said that it a couple of days ago worked fine.

Mr Canis

well i don't have a memory card i have internal memory

Hello Reddan1988,
when you connect the camera, in which mode is the camera? USB or camera
And what says lsusb?

Mr Canis

i have no idea what that means

Hello Reddan1988,
in my case, I have two choices, USB or camera. If I choose "camera", I haven't access to the camera. But if I choose USB, all works fine. Therefore my suggestion is to try USB mode. And more better is to use a memory card, because Linux handled it than as Mass Storage device (SCSI), as like as a external USB Harddisk.

Mr Canis

Hello everyone. I have the same problem, in this case using a Canon Powershot S45 camera that had been working fine with Ubuntu. Nothing has changed, memory card is in, camera is in the only mode it has -- the only new thing I can think of is the updates I typically download for Ubuntu.

When I try to connect to download the photos, I get this dialog box message:

«An error occurred in the io-library ('Could not claim the USB device'): Could not claim interface 0 (Operation not permitted). Make sure no other program or kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device.»

Could there have been a bug in one of those updates that made these devices not work? Or have you figured out another possible answer?

Thanks much.

Specifically, the rules.d entry in https://beta.launchpad.net/ubuntu/+source/libgphoto2/+bug/91250 should solve the problem.

Thank you, Joey, for the answer, but I can't access that page. It tells me it's a restricted site... any other way I can get that info?

Joey, I found the bug reports. I just did a search by ticket numbers. And they did help. It took me a while to figure that out but I had to insert the code for the camera and remove a line of code that apparently made the file for USB connections useless. I hope the experts find an easier fix for those of us who depend on the easy updates.

But thanks, you led me to the right answer...

excellent. Sorry about the beta link. Just remove "beta." for now to get to the normal Launchpad page.
