What is f3UsbHostPhysicalAddress?
This read-only DisplayString value reports the MAC address of the USB device currently inserted in the host port, when the device has one. 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 USB network adapter is plugged into the host port, this OID reports its MAC address so it can be matched against the address seen in the network's ARP or switch tables.
