 a different set of interfaces) the code in all other files should
 automatically adapt to the new endpoints you specify here.
 
-However, the .h files for each interface, which define the API
-visible to user programs, may need to be edited.  At the top of
-each .h file is #if defined(USB_XYZ).  These may need to be edited
-to make the interface API appear to your program.
-
 If you need to create a new type of interface, you'll need to write
 the code which sends and receives packets, and presents an API to
 the user.  Usually, a pair of files are added for the actual code,
