Maybe I didn't follow all of your connection details. The Yamaha PSR-175 does not have a direct USB port. To connect it to a computer, you need to use a MIDI to USB interface cable (such as a Yamaha UX16 or a generic USB MIDI adapter) to connect the 5-pin MIDI OUT/IN ports on the back of the keyboard to a USB port on your computer. I don't recall you mentioning this. Then use the provided Focusrite ASIO driver with BIAB setup in the MIDI driver section for the appropriate input and outputs of the MIDI to USB cable as others have said here.
