I have to write that "cables" are just wires and USB video capture thing are not "cables."

If you were simplifying the term and didn't want to note the electronics in the little box in the cable then it's not a cable but an adapter or video capture cable.

-> And let's dismiss a few more issues with this area.

1. While the USB Video capture "cable" does write capture, all let you VIEW without capturing.
2. ALL such things need drivers.

Can you share why drivers are an issue?
