What do you do with the USB pins if you are not using USB?

Question

I am using the nRF52840 but am not using its USB peripheral. Is it safe just to ground all the pins (D-, D+, VBus)?

Hi Keith 
 You have to ground VBUS. D- and D+ can be left floating, or you can ground them. This is how the reference schematics deals with these pins when not using the USB. 
 
 NOTE: You can not use these pins as GPIOs, as they are USB only. 
 Best regards, 
 Simon
