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 six USB 2.0 ports via ICH4; four ports routed to the back panel and two routed to a USB front panel header. 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 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. 15
