レポートID

  • If you use report IDs, you must pass the ID in the first byte of buffer.
  • If the top-level collection includes report IDs, the caller must set the first byte of the ReportBuffer? parameter to a nonzero report ID.
  • If the top-level collection does not include report IDs, the caller must set the first byte of the ReportBuffer? parameter to zero.
