Hi there. The TB:RB website and users on this forum told me that the GH Les Paul controller would work with this game. So I bought one from someone on Craiglist. Well, it works fine, but only when I have the GH dongle connected... the RB dongle doesn't pick it up. So basically this means that I can use the guitar, but not with a full band... I have to either disconnect the drummer or the vocalist to free up a port for the second dongle. Is this how it's supposed to be? Do I need to go get a hub or a splitter now?
