[1] Reset values that are highlighted—for example, 0—indicate read and write accesses; and reset values that are not highlighted—for

example, 0—indicate read-only.

[2] See Section 8.2.3.4.

The HCD does not usually interact with the PCI configuration space. The configuration

space is used only by the PCI enumerator to identify the USB Host Controller and assign

appropriate system resources by reading the Vendor ID (VID) and the Device ID (DID).

8.2.1 PCI configuration header registers

The Enhanced Host Controller implements the normal PCI header register values, except

the values for the memory-mapping base address register, serial bus number and Device

ID.

8.2.1.1 Vendor ID register

This read-only register identifies the manufacturer of the device. PCI Special Interest

Group (PCI-SIG) assigns valid vendor identifiers to ensure the uniqueness of the

identifier. The bit description is shown in Table 4.
