Hi,

 

What version of the nRF52840 DK do you have? Early preview kits with engineering A had many erratas on the USBD and support was dropped for this revision in SDK v15. 

Have you tried using different SD cards?

It should enumerate several MSC drives regardless of if it gets a connection with your SD card. Do you see any of these?

 

Best regards,

Håkon
