usb-storage driver does not recognize my digital camera

I have a Canon EOS400D Rebel XTi, and I'm having some trouble getting it mounted as a storage device so that I can grab photos from it. Any help would be appreciated.

When i plug in the camera, I get this:

OK, what specifically are you doing to try and read it, and what, if any, errors have you seen? As far as the kernel goes, besides "USB Mass Storage support", you may need to enable "SCSI disk support", though it probably is already. You could try adding "SCSI generic support".

Do you want automounting feature?
If you can't see any errors there then the camera is working fin.
For automounting you need something like gnome-volumemanager or the kipslaves from kde or ivman

Ahh, well. In theory, when I plug in the camera. The usb-storage driver should recognize it as a mass-storage device, create a device in /dev as if it were a flash USB key (or something similar) and then I would be able to mount it manually, or with gnome-volume-manager.

However, none of this happens, no device is created in /dev. The only thing that happens is that the system registers a new USB connect / disconnect event, and assigns / frees the address.

I also tried using gphoto2 to auto-detect the camera, but that came back with no devices found.

When I plug the camera into my windows box (I HATE using windows... which is why I care so much about fixing this!) the camera is autodetected, and I can transfer images off. So I must be doing something wrong in Gentoo.

it should show up as a /dev/sdax node... besides usb-storage and some scsi stuff, you shouldn't need anything to mount it, unless its one of those cameras which fakes as a mmc reader.

nope, usb-storage doesn't create an sda, sdb, sdnx... node.
Nothing.

What makes you think that your camera supports usb-storage?
My canon is3 uses PTP. You can't mount it, but gphoto2 (I
use the digikam frontend) works fine (after you get the groups/
permission stuff right).

Well. For the time being, assuming it's not supported by usb-storage... what do I need to do to get the groups set up right for digikam?

Thanks,

I just realised that I am actually using gtkam, not digikam. Does anyone know how to set up permissions for that? I've searched the online documentation, and haven't come up with anything that works.

I can access the camera via root, but not via my own user. I have tried adding permissions to plugdev, and camera.

Thanks!

Just tackled this same thing... I had to put gtkam, gphoto2, and libgphoto2 in my portage.keywords... 400D is supported in 2.3 but 2.2 was the latest 'stable' in portage... for AMD64 at least...
