3.9 USB 2.0 Ports
The Hudson-E1 contains three Enhanced Host Controller Interface (EHCI) host controllers, which support up to
fourteen USB 2.0 high-speed root ports. USB 2.0 allows data transfers up to 480Mb/s using the same pins as
the fourteen USB full-speed/low-speed ports. The Hudson-E1 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.
The CMx-GF uses six of the fourteen ports. They are available for the application on three USB connectors,
each providing two ports using a different EHCI controller for full USB performance. A standard adapter cable
is available, too.
A USB keyboard will function under MSDOS without special driver software.
Ports 0/1 are powered in S3 to support wakeup from keyboard and mouse.
Note: Not all USB keyboard models are supported.
