There are some boards and samples in the tree that use the CDC ACM UART as the default serial backend, just like a real UART controller would. The new device stack requires more detailed configuration than the old one. In order to use the CDC ACM UART as the serial backend with the new device stack in the same way as with the legacy stack, we need to provide a solution to initialise and enable the CDC ACM UART at boot time. We cannot use snippets as they do not support Kconfig files or source code. Shields would be an option, but they cannot be used for virtual devices such as the CDC ACM UART. The remaining solution is to put the code and Kconfig file for it in the subsys directory. Allow CDC ACM UART instance and USB device stack to be initialized and enabled at boot time and to use it as serial backend for logging or shell.
