Communication Endpoints
There are two communication endpoints and endpoint 0 is used for the enumeration process.
Endpoint 1 is a 64-byte Bulk OUT endpoint and endpoint 2 is a 64-byte Bulk IN endpoint. SAM-
BA Boot commands are sent by the host through the endpoint 1. If required, the message is split
by the host into several data payloads by the host driver.
If the command requires a response, the host can send IN transactions to pick up the response.
