I need to import from a DV tape on a Canon video camera to a laptop running Windows 7 Home Premium.  While the process to date assumes a Firewire connection on the computer, this computer has only USB-2.  There is a Firewire and a USB port on the camera, along with the analog output port.  Is there any way to use the camera's USB to computer USB connection to download the tape?  How do I transfer the tape to the computer without the Firewire on the computer?
