Hy, i have a problem with xhci controller it says port 15 unspecified connection failure even if it is nothing connected in any usb ports, I even disconected the frontal ports. This is my 3rd motherboard with this problem. In windows 7 i don't have any of this error, everything works great but in windows 8.1 and 10 i have this problem. My bios is updated, i talked with asus, microsoft but the problem isn't gone. When i rma'ed the second motherboard they could not find the root of my problem and they exchanged my motherboard with a new one. The drivers of the chipset is the latest. the error that gives me on Port15 VID:0000,PID:0000- all usb works ok but it bugs me that i don't know form where i get this error on port15 like i said even there is nothing connected on the ports. Would this be an enginering problem or a driver problem?

Hy Carlos, i talked with asus, microsoft and they couldn't help me the result is the same. This is the 3rd motherboard that has the same problem. The problem is gone only in windows 7. This is a engenering problem of the board or a driver problem?
