I can't seem to have both the drums and microphone recognized when using rockband. Both work when plugged into USB port 1, but neither work with usb port 2. I'm trying to run rock band using neogamma R9. I have 249 installed with base 37. I also have 223 installed with 37. Rockband will recognize my guitar and whatever is plugged into usb port 1. I'm on system 4.2. Anyone know what I might be missing to get both instruments to work? Any advice would be much appreciated.
