So I am the person IGURU42 was referring to that is doing all the modifications. The one thing I did not do prior to modification is test the controller. It currently will show no function of the joysticks or triggers when tested in Windows XP on its own. I made sure I have tested the second controller and it definitely works. My only recourse is to remove all modified connections to the controller and test it again, which I am not looking forward to doing, but I will have to do it anyway in order to transfer the XIM2 board to a known good controller and have at it again. Does anyone have any insight to this at all? I have checked all my solder connections and they are clean and no bridges. All connections go to the locations pointed out in the install guide. I tested the +5V and GND connections and they are okay, so I don't think this is attributed to the XIM2 board causing any odd issues due to not being powered. The odd thing is it did pass the stress test just fine when I ran it the first time, and then failed when I got the controller home. Maybe I am using a bad controller and never knew it?
