Please help... USB port not working (5DMK2)

[trap74]

hello, can someone help me with my problem?
My usb port stop working, i dont' find the original ifc-200u usb cord for my camera (don't know if it is that the problem), tried lots of cord but none of these work.
When i connect the cord to my mac 10.8 and EOS 5DMK2 solution-disk29.1a camera get busy for some seconds and after that nothing happen.
tried to reset camera, remove bootflag, downgrade firmware changing cf cards etc etc.
I've inspected the female connector on the camera and pins are not bend.
I don't know if the problem is related to some ptp property in nvram or the camera get bricked, before open the camera and check the usb pinout on the pcb i will check with ML user but i dont find somethink useful on the forum.
I have no problem to desolder end resolder (SMD solder station) or changing the entire mainboard or sending to service after reset.
Camera works good without problems but no usb and no connection menu on the camera, i also cheched the usb bus on my mac but no connection.
Is there any way to log or monitor the usb connection from the camera?
I installed startup log from dignostic tools how to attach it in the post?
I can't live without ML, i love it.
Thnks in advance
