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
