How to connect Sony camera HDR-XR 160E to a computer? Do I have to use any port and maritime bureau?

Select USB, then the computer looks for new hardware, and that's it.

Pay attention to keep enough power after connecting the computer, and it is best to connect an external power supply. If power is cut off in the middle, it is very dangerous, which may lead to data loss or even failure to start; In addition, after the operation is completed, you must choose to exit the USB connection of the camera. You can't directly unplug the cable, and you can't directly disconnect the USB connection on the computer side.
