First off, I'm using USBLoader GX with a WBFS partitioned hard drive. I've updated using Pimp My Wii 2.02. I have two different microphones (one is a GH mic, the other is the Disney Sing It microphone). I've tried loading under 222, 223, 249, and 250 all with no success. The game will act as if I have a microphone but doesn't pick anything up from it. I've tried using uLoader 5.1 with no success. All other instruments work, so I think it has to do with the USB port itself. Any suggestions would be welcome.
