My cable that runs from the front panel of my case to my motherboard was always coming loose. Finally, the last time I went to reconnect it I accidentally broke off the pin titled (IntA_P1_D+) on my motherboard. I understand that the function of the pin is "USB 3 ICC Port1 D+ (USB 2 Signal D+)" but what does that mean? My USB 3.0 device seems to be working fine, but my USB 2.0 stick only works on one of the ports now. I am guessing from this that only USB 2.0 function is broken but I don't want to use the port if it could potentially corrupt my USB 3.0 drive. Any help?
