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.

Creates a new USBIsochronousInTransferPacket object with the provided status and data fields.
USBIsochronousInTransferPacket.data Read only Read only Experimental
Returns a DataView object containing the data received from the USB device in this packet, if any.
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.| Specification |
