Follow the procedure in "Making the Connection to
a Computer" (p. 16) to connect the VR-3EX and a
computer using a USB cable.
2.
Put the VR-3EX in a state capable of outputting video or
audio.
Operate the VR-3EX to get it ready to output video or audio to the
computer.
3.
On the computer, confirm the input from the VR-3EX.
Start a program that supports USB video class or audio class, and
