Hi, I'm just wondering if this actually exists, because I haven't found one that does. I've bought a GT3 RS steering wheel, and from several sources I've read that it works much better with an add-on USB card (I'm not sure why, but enough people have said this that I have to believe it). What I'm looking for is an internal USB card, either PCI or PCI-E, ideally molex powered but not essential and with the same header as case USB ports use, so I can simply plug my front USB ports into it. Is this possible?
