Hi flip53, welcome to 7F!
Ambimom is correct about the camera, and you might also be able to do that with the scanner, but scanners, printers, etc. usually like their own software.
I'd say plug the camera in with the cable provided, turn it on.
Then open Explorer, and see if it is recognized below your HDD in the left column. Camera's can be hot swapped.
With the scanner shut down your machine, plug in the scanner, then re-start your machine, and see if Windows 7 recognizes it.
Most scanners, printers, etc. are done this way.
Here is a list of:
