Problem regarding experimental_bootloader_secure_usb on nRF52840

Hi,

I am implementing experimental_bootloader_secure_usb code example on PDK PCA10056 V0.9.2 using Sdk v14.0 and also tested with Sdk v14.2 but in both cases Windows 10 do not recognize Usb and showing an error " USB Device not recognized". But it works well when using J-link RTT viewer. I know someone else also had same problem devzone.nordicsemi.com/.../

Is it really a hardware issue or there is some work around ?
