Table - µC/USB-Device Module Dependency indicates that all the µC/USB-Device classes are optional because there is no mandatory class to purchase with the µC/USB-Device Core and Driver. The class to purchase will depend on your needs. But don’t forget that you need a class to build a complete USB project. Table - µC/USB-Device Module Dependency also indicates that µC/OS-II and -III Core and Port are optional. Indeed, µC/USB-Device stack does not assume a specific real-time operating system to work with, but it still requires one.
