nrf52840 - USB functionnality without VBUS

[aboulerie]

Hello,

Due to a routing error, the VBUS pin of the nRF52840 is connected to the GND.

The software works on the devkit but not on my prototype.

From what I saw in the product specification, it seems that it could be caused by the unconnected VBUS pin.

Is there a way to make it work by changing some configuration in the software ?

Thanks,

No. The USB data pins are powered via VBUS.
