I create a PDO for a usb device on top of which the device function driver is loaded.
My problem is that I want my PDO to inherit the PNP properties from the function driver. The logic being that I want the ‘Safely Remove Hardware’ icon to appear on my toolbar. I can only do this if I set the PNP properties using WdfDeviceSetPnpCapabilities when I create my PDO. What am I doing wrong?
The safe removal property of a dev node really belongs to the FDO of the stack, not thePDO

Yes, so if I create a PDO and don’t set PNP properties the device should show up with a ‘Safely Remove Hardware’ icon in the system tray, correct? This is what I assumed, but it does not happen. The icon only shows up if I explicitly set PNP properties when creating the PDO.
What sort of device?

I create a PDO for a flash disk (USB).
