Problem solved: Kodak DX6490 on Sarge/2.6/udev
FYI, I finally got the camera working (see millions of earlier emails on
The solution was simple: add my user to the 'camera' unix group.
The things that tripped me up were:
- I had the misconception that my camera supported both USB mass storage
and the PTP protocol. The truth is it only supports PTP. So the fact
that UDEV was never told about the kernel creating a device such as
"/dev/sda1" for the camera wasn't a problem after all - no such device
ought to be created for this camera model.
- I didn't realize that if you're going to access a camera via PTP, then
that's (typically) accomplished via a user-space USB driver that the
application (such as digikam) makes use of. So the fact that I never
saw the kernel load a module for this camera isn't a problem. (BTW, the
PTP library that many apps like digikam or gphoto use is 'libgphoto2'.)
Thanks for everyone's help in the process.
