The USBInTransferResult interface of the WebUSB API provides the result from a call to the transferIn() and controlTransferIn() methods of the USBDevice interface. It represents the result from requesting a transfer of data from the USB device to the USB host.

Constructor

  • {{domxref("USBInTransferResult.USBInTransferResult", "USBInTransferResult()")}} {{Experimental_Inline}}
    • : Creates a new USBInTransferResult object with the provided status and data fields.

Instance properties

  • {{domxref("USBInTransferResult.data")}} {{ReadOnlyInline}} {{Experimental_Inline}}
    • : Returns a DataView object containing the data received from the USB device, if any.
  • {{domxref("USBInTransferResult.status")}} {{ReadOnlyInline}} {{Experimental_Inline}}
    • : Returns the status of the transfer request, one of:
      • "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.
      • "babble" - The device responded with more data than was expected.
