Location IDs can be obtained using the utility USBView that is available from FTDI. To get the Location ID for a specific USB port, run USBView and plug a device into the port that is required. From the menu select Options > LocationIDs. Press F5 to refresh the display and the port numbers are replaced with Location IDs of the form LocXY where X and Y are hexadecimal digits. XY is the Location ID that is used in the LocIds field as described in the previous section.
