Hacking USB Loader GX with wavebird controller?

[Therobman]

I have a few wavebirds i use with nintendont for my GC games. If i launch nintendont and a game my wavebirds controllers work as they should. The issue i am running into is when i launch a gamecube game from USB loader gx. It launches nintendont then the game but my wavebirds do not work. If i plug in a regular gamecube controller it works fine. Am i missing any setting or something i have to have enabled, or is this just an issue when launching a gamecube game from usb loader and using a wavebird.
