The USBIsochronousInTransferPacket interface of the WebUSB API is part of the response from a call to the isochronousTransferIn() method of the USBDevice interface. It represents the status of an individual packet from a request to transfer data from the USB device to the USB host over an isochronous endpoint.


USBIsochronousInTransferPacket() Experimental

Creates a new USBIsochronousInTransferPacket object with the provided status and data fields.

USBIsochronousInTransferPacket.status Read only 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 an isochronous endpoint does not need to be cleared.
  • "babble" - The device responded with more data than was expected.
