USB
The board provides up to eight USB 2.0 ports, supports UHCI and EHCI, and uses
UHCI- and EHCI-compatible drivers (four ports routed to the back panel and four ports
routed to two front panel USB 2.0 headers).
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.

SATA Support
The board provides two SATA interface connectors that support one device per
connector.
The board’s SATA controller offers independent SATA ports with a theoretical
maximum transfer rate of 3.0 Gb/s on each port. One device can be installed on each
port for a maximum of two SATA devices. A point-to-point interface is used for host to
device connections, unlike PATA which supports a master/slave configuration and two
devices on each channel.
For compatibility, the underlying SATA functionality is transparent to the operating
system. The SATA controller supports IDE and AHCI configuration and can operate in
both legacy and native modes. In legacy mode, standard ATA I/O and IRQ resources
are assigned (IRQ 14 and 15). In native mode, standard Conventional PCI bus
resource steering is used. Native mode is the preferred mode for configurations using
the Windows Vista* operating system.
