  • "ok" - The transfer was successful.
  • "stall" - The device indicated an error by generating a stall condition on the endpoint. A stall on the control endpoint does not need to be cleared. A stall on a bulk or interrupt endpoint must be cleared by calling clearHalt() before transferIn() can be called again.
