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.
USBInTransferResult() Experimental
Creates a new USBInTransferResult object with the provided status and data fields.
USBInTransferResult.data Read only Experimental
Returns a DataView object containing the data received from the USB device, if any.
USBInTransferResult.status Read only Experimental
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.| Specification |
