+ 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
