USB CDC ACM example is not working in 52840

Hi Nordic, 

While testing USB CDC example with nRF 15.3.0 in PDK board, I see USB is not recognized. I have gone through the same issue posted in Forum. Is it the issue with board? I am using v0.9.0 PDK board. Need help in resolving this.

Thanks,

Hi,

Engineering A version of the nRF52840 is not longer supported, starting from SDK 15. See this compatibility matrix. Engineering A is used on the 0.9.x versions of the nrf52840 (P)DK (PCA10056). See this link. The "preview" DK is no longer recommended for development. Please order a new nRF52840-DK. New versions of the DK uses the production silicon(IC revision 1 and 2).
