Wired and Wireless controllers used simultaenously

[Vold3]

I have an Xbox 360 wireless receiver with wireless controller as well as a wired controller. However, I'm having problems getting both controllers to work simultaneously as gamecube controllers. I have each controller on separate xinputs (1 and 2) and they're set to the same profile. They work together fine on pc games, etc. Sorry if this is explained elsewhere. Using latest Dolphin build.
