This is a function of how the device presents itself over the USB, and also possibly what file format it stores pictures in.  Some modern cameras can be switched between being a "camera" or "file system" over the USB.  Check the user manual.

To guarantee you see the pictures in part of your file system, take the memory card out of the camera and connect it via a separate "card reader".  That takes all the camera's fancy firmware out of the loop and lets the OS see the raw files.

One problem you might run into then is that the files are not in a standard format.  If so, you'll have to use software from the camera manufacturer to read the image files and convert them to something standard, like JPG or TIF.  Camera manufacturers generally have free software for that purpose, although it can be tedious to use if you just want at the raw image data to use your own software with.

High end image manipulation software often has built-in support for the proprietary formats of major camera manufacturers.  Such programs can then read the raw files off the flash card directly.
