FW: Subsystem Vendor ID assignment

[Keith Jasinski <jasinski@mortara.com>]

To further elaborate (or exacerbate) the question:

The recent release of V2.2 of the spec requires the implementation of
Subsystem Vendor and Device IDs.  Why?  Is the sole purpose to allow
multiple uses of the same core (PLX, AMCC, Motorola, Intel, whoever)
without replacing their Device and Vendor IDs?

Since the SIG does not assign Subsystem Vendor IDs, just Vendor IDs,
does anyone who has a Vendor ID also have a Subsystem ID (ie: the same
number)?

When Windows does a device recognition, does it have to match all 4 IDs
(both vendor and both device) to recognize a device?

In our case, we are either creating our own core or replaceing the
device and vendor ID with our own.  Since V2.2 requires subsystem vendor
and device IDs, do I just replicate the vendor and device IDs in the
subsystem section?

Thanks in advance,
Keith
