Hi-Speed USB 2.0 Support
NOTE
Computer systems that have an unshielded cable attached to a USB port might not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable.
Use a shielded cable that meets the requirements for a full-speed USB device.
The desktop board supports up to eight USB 2.0 ports via ICH5; four ports routed to the back
panel and four routed to the internal USB 2.0 headers. USB 2.0 ports are backward compatible
with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer
rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports to USB 1.1 operation. This
may be required to accommodate operating systems that do not support USB 2.0.
NOTE
USB devices are limited to USB 1.1 transfer rates prior to operating system and driver
initialization.
