Intended to allow using x16 video cards with x1 slots, and reducing power/space/cooling demands on mainboard. Claim: "No Driver necessary" Can these things possibly work? If they do, it seems to me that this would be a great way to add additional general purpose PCIe slots to any computer that has USB ports, which nearly all do these days. If no driver is needed, they should work with any OS. Obviously there is a speed limitation, but many applications can live with that. Sounds too good to be true.
