I'm not sure if this will help you out or not, but this is what I do with my Sony Digital8 HandyCam (is a video camera that takes digital stills). It has a USB lead and uses a memory stick, so ...
1. mkdir /mnt/digicam (you'll need a mount point)
2. chmod a+r /dev/sda1 (change permissions to access the device)
3. ln -s /dev/sda1 /dev/digicam (make a symbolic/soft link)
4. Edit /etc/fstab and add line: /dev/sda1 /mnt/digicam auto auto,user 0 0
Now, once this is done, when I want to view photos on my memory stick I can mount the camera (i.e. mount /mnt/digicam) and either cd to the correct file directory (i.e. cd /mnt/digicam/dcim/100dcf <-- I think, this is using my human memory

) and can download onto my hard drive or view using GQView on the stick itself.
Hope this helps.
