I haven't been following this thread to closely, and I use gphoto2 rather
than gphoto, but the only way I could get it to work with my Kodak DC3400
is as follows:
1- usbcore and usb-ohci must be loaded (I think that usb-ohci is
specific to the USB controller hardware on your system, for some people
usb-uhci or another similar module may be required instead).
2- usbdevfs must be mounted
3- the usb module for my camera must NOT be loaded (gphoto2 talks directly
to the camera, if the module is loaded, it can't get access). Everytime
I plug my camera in, the module is automatically loaded, so I have to
manually unload it before I can access the camera.
4- I have to run gphoto2 as root
Perhaps this will give you some ideas for things to try.
