5V VCC
USB cable plugged in to MC Cthulhu, worked fine on PS3/PC

Now:
360 USB cables soldered as normal, above four cables cut, no PS3 function
Stick is recognized on 360/PC, control panel shows all buttons functioning as normal (Except start+select as guide)
except inputting five buttons simultaneously seems to trigger all of the buttons (5 buttons, 4 + one joystick, or 3

+ one joystick diagonal)
