So to recap. I did blow the 5V mains from my USBs by allowing 220AC, or a part of it, on hte usb port. I did some tests, and all the data lines are intact, at least for USB2.0. I did had one remaining USB that does not work anymore. Given the fact that this was the USB that made contact with the mains, I think that the some of the circuit was already damaged, and today when I was doing my testing I did pull more current from it(with an external HDD that did not spin BTW) and caused more damage. Now this port is reading 3.1V instead of 5V and ofc no device works with this. My ideea is that I destroyed some regulators or some fuses, so if you could help me look for them that would be great. I dont really have experience with parts this small, or complex.
