i get the vid and pid of the usb devices plugged into my system using WMI.

Now i want to get the drive letter corresponding to the device vid and pid i retrievd.

code

 hres = pSvc->ExecQuery(
        bstr_t("WQL"), 
        bstr_t("SELECT * FROM Win32_USBControllerDevice"),
        WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
        NULL,
        &pEnumerator);

if (FAILED(pclsObj->Get(L"Dependent", 0, &vtProp, 0, 0)))
{
      cout<<"The specified property is not found."<<endl;

}
else
{
   wcout <<vtProp.bstrVal << endl;

}

i get like below

\NJ96\root\cimv2:Win32_PnPEntity.DeviceID="USB\VID_1A8D&PID_1000\35809402 0874450"

how can i map DRIVE LETTER to my above output using the WMI

please help me out
