So it's that time when we think about things to buy for our kids. Currently I'm using USB loading for our games. I want to get my son DJ Hero 2 but don't quite understand how 1 USB port would be efficient. Can someone explain how these Rock Band type of games work as far as say using drums, keyboard, mic, guitar on 1 USB port? Is there some kind of USB hub that connects from that or? So my concern is DJ Hero requires 2 turn tables and a Microphone (that's just LOL saying that for some reason. Long live Beck!) Anyhow, are these all gonna work off a single USB? If so can whomever is answering explain the technology I.E. USB hub, USB chaining. Please don't just say yes it'll work Merry Xmas lol..
