820 2936 usb overvoltage

820-2936
one usb when plugged in says usb overcharged error. trackpad also has issues.
there are random spots of corrosion here and there but nothing that is on the usb line. i've cleaned out the board and replaced u2600 u5701 - still no usb

Which kind of issues on trackpad?
TP and USB ports go to USB hub and this points to U2600 area problem.
If one port still works, U2600 must be good.
Probably corroded traces/components around it...
