* One major issue with CDC-ACM is that it requires two Interface descriptors,

* which will upset most hosts when part of a multi-function "Composite" USB
|

* device, as each interface will be loaded into a separate driver instance. To
|

* combat this, you should use the "Interface Association Descriptor" addendum to
