I've discovered gtkam on ubuntu, and i wanted to use it on debian, but it seems that the usb system has some problem with the camera... Here is the thread url:

--------------------------

And here is a copy of it if you don't want to follow the link

I'm under debian testing, and i've tried to plug my camera on the usb port... i works fine on ubuntu, but on debian i got some problem...

it recognizes the camera:
But just for 1 second and then nothing:
So when i launch gtkam and try to auto-detect it, it just says "no camera detected."

Any idea ?

dude, i personally haf trouble getting gphoto2 to run as a normal account user in Sarge.
i did a search on google and i realised that i m not the only one.
if gphoto2 cant work, dun expect gtkam to work. In the end, i download my photos as Root.

login as root in konsole and see whether debian recognises ur camera.

gphoto2 --auto-detect

if it does, then you can get the photos by

gphoto2 -P

the disadvantage is you haf to chown, chgrp and chmod 755 your photos later.

Arf, you're right... even gtkam works when you're root (except for some segfault), which is normal because it uses the same library than gphoto...

It seems that the problem comes from the fact that debian says that the usb device should be used by the root only... It has it's advantages and inconvienients... it's safer, but damn not user-friendly!

Well, finally it works! That what's important!

Thanks damienduff!

"4.3.2. Setting up linux-hotplug" in http://gphoto.sourceforge.net/doc/ma...sions-usb.html covers setting up user permissions.

A shorter version is here: http://nift.freeshell.org/camedia.html

Even though it says to use this in fstab: usbdevfs /proc/bus/usb usbdevfs defaults 0 0
I use this line: usbfs /proc/bus/usb usbfs defaults,devuid=0,devgid=106,devmode=0666 0 0
106 is my group for usb.

Add yourself to the camera group:
"adduser username camera" (as root).

makuyl: it seems that usbfs is already mounted (try a mount -l). at least in the recent sarge release... but there is no /etc/hotplug/usb/usbcam.usermap file... i don't see why it is necessary...

yotamk: indeed, when you add yourself to the camera group, the cam devices doesn't disapear from the lsusb command

I just got one last problem... now i can use gphoto2 whithout any problem as a normal user, but when i plug the camera, i have the popup that ask me what to do after having plugged the camera... i push the button "get the images" (or something like that, it's in french here ), but gtkam doesn't launch... i don't understand why..

By the way, thanks for the tips

I suppose the usermap isn't necessary if the camera supports usb-storage. For canons it's needed and using it would allow to plug in several cameras without storage support. If you just use the one that works, you can probably skip the usermap.
BTW, the second howto said: # gphoto2 --print-usb-usermap >> /etc/hotplug/usb.usermap
So the /etc/hotplug/usb/usbcam.usermap isn't necessary either. You have some choises here and several ways work.

The devmode in fstab is to give userrights so you don't have to use it as root, but like I said, the howto also it isn't necessary.

BTW again, I changed the script to set group to users instead of camera.

Hi!
