I just bought a logitech DFP on ebay, and did not come with an instruction sheet. I have it plugged into my ps2, but I don't know how to make it work in the GT4P. The light is on on the wheel but nothing happens. (Plugged it in with USB, is that right?)
Nevermind guys, I find the power supply I didn't have inside the box. It's workin now, and I just am amazed at it. I recommend one to anyone that doesn't have one.
