Programming Interface — RO.

00h = No specific register level programming interface defined.

Sub Class Code (SCC) — RO.

03h = USB host controller.

Base Class Code (BCC) — RO.

0Ch = Serial Bus controller.

Master Latency Timer (MLT) — RO. The USB controller is implemented internal to the

ICH8 and not arbitrated as a PCI device. Therefore the device does not require a

Master Latency Timer.
