Hello.
Have this MSI X99A SLI PLUS gamer pc motherboard, that have ripped IC near USB 3.0 port and now its tripping usb overcurrent signal which stop board from working.

ripped ic is 6pin package with marking

702 4
N

i think it is usb controller or something because it is near every usb 3.0 port

how to get rid of this overcurrent signal?

Post a picture of the ic if you can, It could be a SPN7002D or MTDN7002ZHS6R dual mosfet or maybe ADG702dual cmos low voltage spdt switch

I think this is it? 2N7002DW check the circuit to see if it makes sense.
Here is a pdf I found, check page 25, see if this helps?

Re: ripped IC tripping USB OVERCURRENT

yes it is 2N7002D but traces are gone and dont think i can remake it. anybody know what is good jumper combination between pins?

Re: ripped IC tripping USB OVERCURRENT

You need to trace the ripped trace to the closest component on that line and add a small wire from the new ic's pin to that component. It won't be easy but can be done, there are still a couple traces to secure the ic to the board
