According to the Yamaha site online .pdf manual, your keyboard does not have its own USB connection.

It has standard MIDI In and Out only.

If you are using a USB to MIDI adaptor, THAT is what you must find any drivers for if they don't show up automatically.

Also, with USB, it is important to have it hooked up and recognized by the OS before starting any host program that may use the USB MIDI connect.
