How does EOS 400D connect to a computer?

There are two ways to connect to the computer:

1. You can connect a computer with a data cable (generally a USB interface). After the connection, you need to turn on the camera, and the computer will find new hardware. When you turn on my computer, you will see the icon, and then you can do the next operation, copy photos or take photos.

You can use the card reader to take out the memory card in the camera and put it in the card reader, and then connect the card reader to the computer, so you can copy the photos in the memory card.
