Serial Number Implementation in PCI Express Card/device

NTDEV
1

Dear Sir,

Can anybody explain the following queries?

* What is the use of Serial Number Implementation in PCI Express
Card/device?
* How to test this feature in Microsoft Windows Vista and Windows XP.
* Can we test this feature for a PCI Express device on PCIe single
lane slot (which is on mother board) or do we need to have PCI ExpressCard
port and device to test this feature?
* Is Serial Number feature in PCI Express card identical to iSerial (
and String Descriptors) in USB ?

Thanks in advance,

Madhukar Reddy

Serial numbers provide unique identifiers for a specific device. I believe
they are optional for pcie. No they are not identical to USB serial numbers
as the USB spec defines that functionality and the PCIe spec defines the
PCIe device serial number functionality. If you are testing PCIe features I
suggest that you should get access to the PCIe specifications from the PCI
SIG. Although they are written in an obscure variant of English, with a bit
of work all becomes clear.

IIRC, you must have a serial number for ExpressCards (essentially hot
pluggable devices) while fixed devices in the chassis would not require
the serial number. While the mechanisms between PCIe and USB are
different with respect to how to retrieve the serial number, the OS’s
use of that serial number is the same. If the device has a serial
number is plugged into a different slot, the OS can identify that it has
previously seen the device and will treat it as the same instance.
