Problem with USB DFU when RTT is disconnected

Hi,

I am using SDK v14.1 for nRF52840. The secure_dfu_usb debug example works well when the J-link RTT Viewer is connected. But when the RTT Viewer is disconnected the Windows does not recognize the USB device

Please help.

Update: It looks the issue is resolved in 0.9.3 version of PDK board.

Could you please let me know whether it is a board design issue or an issue with older version of nRF52840?
