Connect the camera and computer using the USB cable that came with your camera, and then turn on the camera. note: If your camera came with an IEEE 1394 (FireWire) cable and your computer has an open 1394 port, you can use 1394 instead of USB.igure: Camera memory card. Insert the memory card into the appropriate memory card slot in the card reader. note: If your computer does not have a built-in card reader, you can use an external USB card reader that is compatible with your camera's memory card type.
