                These functions call directly into operating system functions
                like:

+                 - usbmsc_configure - Called fromo apps/system/usbmsc and

-               Since the corrsponding device drivers may not be present, these
-               cannot be replaced with IOCTLs.  Perhaps they should be support
-               with new boardctl commands?
   Status:      Open
   Priority:    Medium/High -- the kernel build configuration is not fully fielded
                yet.
