[Problem] MC Cthulhu + Imp v2 + Madcatz360PCB no power.

Well, i have the dual mod maked, but it doesnt work, and im a bit scared. I need your help!

I follow this schemes :

This for MC+IMPV2+360PCB (with a TE 360 board):


And this for RJ45 direct wiring on IMPV2:


Well, when all is wired, i make a RJ45-USB cable following:

PIN(RJ45) - COLOR (CABLE)
1 - RED
2 - WHITE
3- GREEN
4 - BLACK

The cable is good maked, i check it with the multimeter (the wires on the PCB's too)

I see 2 things, when i power the imp with RJ45-USB cable de imp, it start to burn quickly :(

If I connect (only) a USB cable to the MC Cthulhu to the PC it works, but not on 360 :( (but in two cases, the leds of xbox button blinks for a second)

I check that the VCC are in good place.

What can i do? i have a local tournament in 4 days! i need your help!

Thanks!!!

Edit: I forget to say, but MC its updated! before start to wiring!
