Original issue's description:
> Update device/usb and its Mojo interface for variable size ISO packets.
>
> To support the WebUSB API our underlying USB library needs to support
> isochronous transfers with full control over the packet size. We also
> need to know the completion status of each packet which was previously
> not available.
>
> This patch updates the interface to match that provided by libusb and
> the underlying platform specific APIs.
