+  Title:       apps/system PARTITIONING
+  Description: Several of the USB device helper applications in apps/system
+               violate OS/application partitioning and will fail on a kernel
+               or protected build.  These include directories:
+
+                 - apps/system/cdcacm
+                 - apps/system/composite
+                 - apps/system/usbmsc
+
+               These functions call directly into operating system functions
+               like:
+
+                 - usbmsc_archinitialize
+                 - composite_archinitialize
+                 - cdcacm_initialize

+                 - composite_initialize
+                 - composite-Uninitialize
+
+               Since the corrsponding device drivers may not be present, these
+               cannot be replaced with IOCTLs.  Perhaps they should be support
+               with new boardctl commands?

   Title:       NxTERM PARTITIONING.
   Description: NxTerm is implemented (correctly) as a driver that resides
                in the nuttx/ directory.  However, the user interfaces must be
