What is a WQL query to get all devices connected to a specific hub?

What is the WMI / WQL Query syntax to get all devices connected to a specific USB Hub?

I can open up a PS terminal and enumerate all USB Hub Devices, as such:

 gwmi Win32_UsbHub | fl *

The output will return a list of all USB Hub device on the system. Here is a sampling of one such device.

Device ID: USB\VID_0451&PID_DD01\6&16FAF918&1&2, PNP Device ID: USB\VID_0451&PID_DD01\6&16FAF918&1&2, Description: Generic SuperSpeed USB Hub    Availability    Caption=Generic SuperSpeed USB Hub    ClassCode    ConfigManagerErrorCode=0    ConfigManagerUserConfig=False    CreationClassName=Win32_USBHub    CurrentAlternateSettings    CurrentConfigValue    Description=Generic SuperSpeed USB Hub    DeviceID=USB\VID_0451&PID_DD01\6&16FAF918&1&2    ErrorCleared    ErrorDescription    GangSwitched    InstallDate    LastErrorCode    Name=Generic SuperSpeed USB Hub    NumberOfConfigs    NumberOfPorts    PNPDeviceID=USB\VID_0451&PID_DD01\6&16FAF918&1&2    PowerManagementCapabilities    PowerManagementSupported    ProtocolCode    Status=OK    StatusInfo    SubclassCode    SystemCreationClassName=Win32_ComputerSystem    SystemName=JMR-ENG-SARAH    USBVersion

Using say the PNPDeviceID for this hub, I would like to get all connected devices, if any to it.

I am totally green with PS and WMI, but I thought of using ASSOCIATES OF as follows:

Get-WmiObject Win32_PnPEntity | select "ASSOCIATORS OF {Win32_UsbHub.DeviceID='USB\VID_0451&PID_DD01\6&16FAF918&1&2'}"

Annoyingly, enumerations do not list parent and children, though Device Manager does list things nicely and has a Parent.

Maybe just the way that I phrased things. Many other ways threw an error, so I did research and saw this syntax. I originally thought of using a gwmi command. In any event, I know from Device Manager that there are connected devices, but the above command yielded a blank screen.

WMI Explorer was not much help.

What would be the SELECT statement to use?
