Edit NUM_ENDPOINTS to be at least the largest endpoint number used.

Edit NUM_USB_BUFFERS to control how much memory the USB stack will
allocate. At least 2 should be used for each endpoint. More
memory will allow higher throughput for user programs that have
high latency (eg, spending time doing things other than interacting
with the USB).

Edit the ENDPOINT*_CONFIG lines so each endpoint is configured
the proper way (transmit, receive, or both).
