All right, here's the update on this shiz; I've still got the problem. I re-downloaded the PS3 controller ini and renamed it to controller.ini, and placed it in the root of my SD Card. As I load up homebrew and the Nintendon't Channel, it seems to be normal. The channel recognized my .Iso, and as I load it, it seems to be normal up until it asks me to insert my controller through the rear USB ports. I've tried both the front and rear USB ports, but both give me an error message of: Init HID devices... Failed! Missing SD:// Controller.ini
Did you accidentally name it controller.ini.ini
This happens when you don't have show hidden files turned on.
