USB PCI Host Controller
8.2.1.11
Subsystem Vendor ID register
The Subsystem Vendor ID register is used to uniquely identify the expansion board or
subsystem where the PCI device resides. This register allows expansion board vendors to
distinguish their boards, even though the boards may have the same Vendor ID and
Device ID.
Subsystem Vendor IDs are assigned by PCI-SIG to maintain uniqueness. The bit
description of the Subsystem Vendor ID register is given in
Table 18
.
8.2.1.12
Subsystem ID register
Subsystem ID values are vendor specific. The bit description of the Subsystem ID register
is given in
Table 19
.
[1]
X is 1h for OHCI1 and OHCI2; X is 2h for EHCI.
8.2.1.13
Capabilities Pointer register
This register is used to point to a linked list of new capabilities implemented by the device.
This register is only valid if CL (bit 4 in the Status register) is set. If implemented, bit 1 and
bit 0 are reserved and should be set to 00b. Software should mask these bits off before
using this register as a pointer in configuration space to the first entry of a linked list of
new capabilities. The bit description of the register is given in
Table 20
.

Description
Base Address to Memory-Mapped Host Controller
Register Space
: The memory size required by OHCI
and EHCI are 4 kB and 256 B, respectively. Therefore,
BAR 0[31:12] is assigned to the two OHCI ports, and
BAR 0[31:8] is assigned to the EHCI port.
