    Hi 

    The USB interface will go into suspend mode automatically, if there is no activity on the bus for at least 3ms. In this mode the USB interface should draw about 400uA, assuming you have the SDK v17.x.x version of the driver. 

    If you want lower current consumption than this you would need to disable the USB interface completely. 

    Best regards
