    Hello Edward

    Thanks for the information. A composite device is when two or more different functions are added to the same physical device. As I see you require a composite which has USB CDC class and another class. Can you specify which is the other class of the device that you are looking for.

    A USB composite device on EK-TM4C123GXL has not been attempted yet as part of TivaWare, so it would need to be done from scratch. Of course we can help you build it, but first we would need clarity on the device classes that need to be supported.
