Thanks, I will try this when I get home in 3 hours.

I suspect, though, that your cameras are not scsi mass storage cameras,
hence are recognized by gphoto out of the box. Nevertheless, I will try.

I have done quite a lot of reading, and I have come to the conclusion that
the real problem is HAL. I have to set up the .fdi file so that the mass
storage device gets automounted.
