How do I get the friendly name of a USB device in Windows?

I'm trying to get the "friendly name" of a plugged-in USB device. I'm using SetupDiGetDeviceRegistryProperty method with SPDRP_FRIENDLYNAME property but the method returns false and sets the error code to ERROR_INVALID_DATA, although everything works fine with other properties, such as SPDRP_DEVICEDESC or SPDRP_MFG.

I checked the registry and the Device Manager and the friendly name exists.

Does anyone have any idea?

UPDATE: What i tried so far:

GUID hidGuid;
HidD_GetHidGuid(&hidGuid);

HDEVINFO hDevInfo = SetupDiGetClassDevs(&hidGuid, 0, 0, DIGCF_PRESENT | DIGCF_INTERFACEDEVICE);

if (INVALID_HANDLE_VALUE == hDevInfo)
{
    AfxMessageBox(CString("SetupDiGetClassDevs(): ")
        + _com_error(GetLastError()).ErrorMessage(), MB_ICONEXCLAMATION);
    return;
}
SP_DEVINFO_DATA* pspDevInfoData =
    (SP_DEVINFO_DATA*)HeapAlloc(GetProcessHeap(), 0, sizeof(SP_DEVINFO_DATA));
pspDevInfoData->cbSize = sizeof(SP_DEVINFO_DATA);
for (int i = 0; SetupDiEnumDeviceInfo(hDevInfo, i, pspDevInfoData); i++)
{
    DWORD DataT;
    DWORD nSize = 0;
    TCHAR buf[MAX_PATH];
if (!SetupDiGetDeviceInstanceId(hDevInfo, pspDevInfoData, buf, sizeof(buf), &nSize))
    {
        AfxMessageBox(CString("SetupDiGetDeviceInstanceId(): ")
            + _com_error(GetLastError()).ErrorMessage(), MB_ICONEXCLAMATION);
        break;
    }
if (SetupDiGetDeviceRegistryProperty(hDevInfo, pspDevInfoData,
                    SPDRP_FRIENDLYNAME, &DataT, (PBYTE)buf, sizeof(buf), &nSize))
    { 
           //display buf
    }
else
    {
        if (GetLastError() == ERROR_INVALID_DATA)
        {
            //display ERROR_INVALID_DATA
        }
        if (SetupDiGetDeviceRegistryProperty(hDevInfo, pspDevInfoData, SPDRP_MFG, &DataT, (PBYTE)buf, sizeof(buf), &nSize))
        {
            //display buf
        }
        if (SetupDiGetDeviceRegistryProperty(hDevInfo, pspDevInfoData,
                SPDRP_DEVICEDESC, &DataT, (PBYTE)buf, sizeof(buf), &nSize))
        {
            // display buf
        }
   }
}

Something like this. As i said, i get the device description and the device manufacturer, but not the friendly name.

This issue mainly goes down to Windows 10 stopping unsigned drivers from installing, even when the 'driver' is just a .inf file that simply references a (presumably signed) windows DLL, but is there to change the "USB Serial Device" into something meaningful to humans, and recognisable by the application software. I've had to re-write 10 different projects because of this issue.

I now have to check for specific VID/PID, however it is not future proof.

Maybe useful information:

  1. In my case I had two network adapters, but the function succeeded only for the adapter that is shown as "... #2" in device manager when SPDRP_FRIENDLYNAME is used.

  2. I could also verify that the other adapter (without the "... #2") does not have a value "FriendlyName" in it's registry data.

  3. This behaviour seems to depend on the O/S. In may case the funtion succeeded always when SPDRP_FRIENDLYNAME is used Windows 10, but only worked for the device that was shown as "...#2" in device manager.

Not all devices have SPDRP_FRIENDLYNAME attribute set. When that's the case, ERROR_INVALID_DATA is expected, it tells you just that.

When they don’t have it, device manager GUI uses another one for display name, SPDRP_DEVICEDESC
