ADSP-CM409F USB Pins to Ground?

Hi,

I have a board design like the following. I do not use USB, so the USB pins are connected to the GND. I know in the manual shows that they need to be pulled low if not using.

My question is that what will happen if they are tied to the GND directly - will this short and damage the processor? If they are left open, would it be fine?

Thanks,

Justin
