What is f3UsbHostSerialNum?
This read-only DisplayString value reports the serial number reported by the USB device currently inserted in the host port. An administrator cares about it because inserting an unexpected or unauthorized USB device into chassis hardware is worth knowing about, and this field lets that be confirmed remotely without a site visit. For example, if a suspect USB device needs to be tracked for warranty or audit purposes, this OID gives its serial number without needing to physically remove and inspect it.
