If you do indeed have a miniDV video camera it has an mini 4 pin Firewire connection.
You need a computer with a Firewire port. The larger closed U shaped one
The cable you'll need would have come with your camera. It'll look like this:
Firewire 4pin to 6pin
You cannot connect the firewire connection to a USB PC port.

On the off chance you were talking about connecting to a USB connection from the camera then you'd use this cable
USB A to mini B
