Opened up the Xbox to fix some trace corrosion. When I put everything back in and booted up, none of my controllers were working. Iv double checked the daughter board several times. Everything is plugged in correctly. On boot up it launches the clock and none of my controllers work in any of the slots. I found out I was atleast getting power through the controller port because when I plugged in my Wingman XB2 it lights up. Any help would be greatly appreciated.
