It's possible that this camera doesn't support being mounted as a USB mass storage device. This web page lists the Canon SD500 as strictly PTP (pitcure transfer protocol: http://www.teaser.fr/~hfiguiere/linux/digicam.html If the SD400 is the same in that regard, then you would have to access the camera with gphoto2, and a front end for it like digikam.
