USB 2.0 Ports
The Southbridge (ICH9) contains two Enhanced Host Controller Interface (EHCI) host controllers
which support up to ten USB 2.0 high-speed root ports. USB 2.0 allows data transfers up to 480Mb/s
using the same pins as the ten USB full-speed/low-speed ports. The ICH9 contains port-routing logic
that determines whether a USB port is controlled by one of the UHCI controllers or by one of the
EHCI controllers.
Four (USB 0/3) of the eleven USB 2.0 host ports are available for the application on two USB
connectors, each providing two ports.
Two USB 2.0 host ports (USB 4/5) are supported at the µDOC. The rest of the USB 2.0 host ports
are provided by Mini-PCIe (USB 6) and Adaptive I/O (USB 7/10).
The ports 0 to 5 uses the first EHCI and the ports 6 to 10 uses the second EHCI.
