- * A session is something inside what any communication occurs.
- * It is expected that sessions would be started right before the transfer
- * and ended - see usb_pipe_end_session() - after the last
- * transfer.
- * The reason for this is that session actually opens some communication
- * channel to the host controller (or to the physical hardware if you
- * wish) and thus it involves acquiring kernel resources.
- * Since they are limited, sessions shall not be longer than strictly
- * necessary.
- *

- * Obsoleted with introduction of usb_pipe_start_long_transfer
- *
- * @param pipe Endpoint pipe to start the session on.
- * @return Error code.
