 According to the reference designs of the nrf52833, VBUS should be connected to GND when the USB peripheral is not used.

&lt;p&gt;It would not be a problem.&amp;nbsp;&lt;span&gt;I guess this should be okay. Also, since the VBUS essentially only powers the USB front-end, it would be fine to not GND the VBUS and to keep it connected to the USB port.&lt;/span&gt;&lt;/p&gt;
