+To modify a USB Type to have different interfaces, start in this
+file.  Delete the XYZ_INTERFACE lines for any interfaces you
+wish to remove, and copy them from another USB Type for any you
+want to add.
+
+Give each interface a unique number, and edit NUM_INTERFACE to
+reflect the number of interfaces.
+
+Within each interface, make sure it uses a unique set of endpoints.
+Edit NUM_ENDPOINTS to be at least the largest endpoint number used.
+Then edit the ENDPOINT*_CONFIG lines so each endpoint is configured
+the proper way (transmit, receive, or both).
+
+The CONFIG_DESC_SIZE and any XYZ_DESC_OFFSET numbers must be
+edited to the correct sizes.  See usb_desc.c for the giant array
+of bytes.  Someday these may be done automatically..... (but how?)
+
+If you are using existing interfaces, the code in each file should
+automatically adapt to the changes you specify.  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.
+
+Finally, edit usb_inst.cpp, which creats instances of the C++
+objects for each combination.
+
+Some operating systems, especially Windows, may cache USB device
+info.  Changes to the device name may not update on the same
+computer unless the vendor or product ID numbers change, or the
+"bcdDevice" revision code is increased.
+
+If these instructions are missing steps or could be improved, please
+let me know?  http://forum.pjrc.com/forums/4-Suggestions-amp-Bug-Reports
