The PCH contains seven USB full/low-speed host controllers
that support the standard Universal Host Controller Interface
(UHCI), Revision 1.1. Each UHCI Host Controller (UHC)
includes a root hub with two separate USB ports each, for a
total of fourteen USB ports.
Overcurrent detection on all USB ports is supported. The

overcurrent inputs are not 5 V tolerant, and can be used as
GPIs if not needed.
The PCH'S UHCI host controllers are arbitrated differently

than standard PCI devices to improve arbitration latency.

(EHCI) host controllers which support up to fourteen USB 2.0
high-speed root ports. USB 2.0 allows data transfers up to 480
