If when you press the ASCOMPAD NSEW buttons the mount does not move make sure the ASCOMPAD is connected to POTH. It should be no different than pressing the POTH buttons on the screen. It sounds like the gamepad is connected to the ASCOMPAD program as it responds and maps the buttons as you said. The problem appears to be the connection between ASCOMPAD and POTH. When you use the chooser in ASCOMPAD make sure you choose POTH, not the PMC8.Telescope driver.
