1.5.1 USB
The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and
EHCI-compatible drivers.
The ICH7 provides the USB controller for all ports. The port arrangement is as follows:
• Four ports are implemented with dual stacked back panel connectors adjacent to the audio
connectors. These connectors are yellow, indicating that they support USB anti-theft circuitry.
• Four ports are routed to two separate front panel USB connectors. These connectors do not
support USB anti-theft circuitry.
NOTE
USB anti-theft circuitry requires the use of Intel
®
Platform Administration Technology software.
Contact your Intel representative for more information.
NOTE
Computer systems that have an unshielded cable attached to a USB port may not meet FCC
Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the
requirements for full-speed devices.
