[nRF52840] Trace routing via D+ or D- pins.

Question

Hello, 
 
 Is it possible to route GPIO trace via D+ or D- pin when USB is not used, please? We have VBUS connected to GND. 
 
 Kind regards, 
 Krzysztof

Hi Krzysztof, 
 My initial thought was also to reply "Probably not". I have now checked with other team members who say it is not recommended. VBUS, D+ and D- belongs to a different power domain than the GPIOs and also have internal hardwired circuitry. 
 Best regards, 
 Håkon
