De obicei USB-urile merg direct in southbridge.Mai sunt intercalate pe traseu ceva bobine pentru reducerea interferentelor si eventual ceva diode de protectie pentru supratensiuni.La unele modele de laptop cand sunt mai multe USB-uri necesare si nu sunt suficiente cele existente in southbridge se mai foloseste un integrat cu functie de hub usb,un port usb al southbridge e conectat la el si acesta ofera alte cateva porturi USB.In alte situatii se folosesc controllere dedicate.cauta pci to usb sau pcie to usb chip.
