This identifier is part of a larger system. The most complete location path in modern Windows, often hidden from the average user, looks something like PCIROOT(0)#PCI(0100)#USBROOT(0)#USB(3)#USB(9) . The "Port_#XXXX.Hub_#YYYY" format is essentially a simplified but vital summary of that final connection. "fqid": "port-0009
