Hi Don.
I have the same mount. Check to what COM port number your mount is assigned(Control panel -> Hardware and Sound -> Device Manager) and make sure that in synscan pro app connecting settings you have the same COM port selected.
Also, I do not know what is your setup, but if your mount will be powered by batteries, and you will connect it by USB, then I suggest to turn off wfi on your mount to lower power consumption. You can do it in synscan pro app wfi connectin settings - will be accessible when you connect your mount by wfi(!).
You do not need hand controller at all... I am controlling my mount in NINA together with Stellarium using USB 3 ports and cables with no any issues
