What is the right way to connect digital piano Yamaha P-45 to UR22C?

Digital piano Yamaha P-45 has USB-B output.
UR22C has midi inputs and XLR/Phone input.
I didn’t manage to find cables USB-B → MIDI nor USB-B->XLR nor USB-B->Phone jack.
So I am quite puzzled now.
Does anyone know how I could connect my piano with USB-B to my UR22C?

Hi @potan89
The simple answer is, you connect the P-45 to your computer via USB, NOT to your soundcard. Download the driver for your piano here:

If you want to connect the P-45 to your UR22c you need to use the headphone out.
