Usb 2.0 Port Configuration (Optional) - Intel D850MVSE Specification

Intel Desktop Board D850MD/D850MV Technical Product Specification
1.8.2.2 USB 2.0 Support (Optional)
NOTE
The USB 2.0 option is currently available only on the D850MV board.
The D850MV board supports USB 2.0 using the NEC PD720100 USB 2.0 host controller, which
is a manufacturing option. The port routing is implemented as shown in Figure 8. The NEC
PD720100 controller is connected through the PCI bus and provides support for up to five USB
ports:
Two ports implemented with stacked back panel connectors, adjacent to the audio connectors
Two ports routed to the front panel USB connector
One port accessible through a CNR add-in card
For more than five USB devices, an external hub can be connected to any of the ports. D850MV
boards with the USB 2.0 option fully support OHCI and EHCI and use OHCI- and
EHCI-compatible drivers.
NOTE
The USB 2.0 option requires an operating system that officially supports USB 2.0. USB 2.0
support has been tested with Windows 2000 and Windows XP drivers and is not currently
supported by any other operating system.
