So, I'd been having no end of problems trying to get my capture card set up. I've almost solved them, but the Game Capture HD software says it needs to be connected to a USB 3.0 port to work. It would appear that all the ports on my PC are USB 2.0...so how can I change this situation? Like, add a 3.0 port or adapt one of the 2.0 ports to 3.0, somehow.
