Problem With Xbox Need Help Asap!!!!

hey i was gonna play multiplayer halo 2 with some freind today with 4 controllers and realised that my 4th controller port does not function anymore. i tried putting a different controller in it that i know works and it wouldn't detect it either.
does anyone know a fix? i can't go back to microsoft with it cuz my box is moded and i don't wanna get a new one cuz i don't wanna go through the hassle of re-modding it.

There's no such thing as a "software" fix for this.
Basically the Xbox is using a slightly modified USB controller and yours sounds busted (or shorted). Check the wire connectors first for "breaks". If you find none, you'll have to replace 'em.
On the V1.0/v1.1 Xbox'es once you find the part they are easy to replace.
Go to xbox-scene for spare parts.

yea i know there is no software fix. i was expecting to have to open the xbox.
i searched the xbox-scene site already but din't find other ppl with the problem or tutorials to fix it.
is there any diagrams or tutorial you are aware of that you can post?
would be greatly appreciated

i think i might have found a solution
