USB and i.Link cables are not the same thing. What Sony call i.Link everyone else calls Firewire, DV or IEEE1394, and it is a different standard from USB with different connectors.
This type of camera usually downloads better with a Firewire (DV) connection. Some mini-DV cameras only use the USB connection (if they have one) for stills and can only download video by Firewire. This is because you have to play the tape into the computer, not just copy a file. If you are trying to use a USB cable for video download, then it won't work for this camera. The driver is not the problem, this model is not on the Sony list of cameras that will download video over USB.
Most PCs have a USB port, but no Firewire port. Macs often have a Firewire port but may not have USB. As most Windows PCs do not come with this interface, you might need to fit an add-on Firewire interface card. This will come with a driver for the card.
Suitable Firewire (DV) cables can easily be found on Amazon or eBay. You will need the kind with a small (four pin) connector at one end and a larger (six pin) connector at the other. My camera came with the correct lead.

You will need to select Windows as the operating system, then Mini-DV as the camera type, then select the type of connection. As you will see, the USB option warns that it won't work with many Mini-DV cameras.
