I am using the MCUxpresso SDK version 2.8.2 and MCUxpresso IDE version 11.2.0. MCUxpresso Config tool version 8.0.
I have added the USB device driver/middleware packages. But still the Config tool claims that "Component USB device is missing in the project". Also the "USB common not found in the toolchain/IDE project.".
But as far as I can investigate, they are added to the project (and it compiles!!). The context menu "Add SDK component" works, but does no difference.
I believe this is "just a bug", and I safely can ignore it.
