lsusb should give you some idea of where the camera is appearing on the 
device list. Then you could try mounting that.

I would go with the flash reader instead - they're very low priced. I 
have one that reads about 8 different card formats, and Linux has no 
problem with any of them.

Another reason to use an external reader is that when you plug into your 
camera, your camera is using its battery - sometimes at a prodigious 
rate - and you could easily have the camera battery die while you're 
using it.
