Subject: [usb] transfer data through iso endpoint
Hi,

I have a question about transferring data through isochronous endpoint. Suppose a device has an iso-in
endpoint, if it gets an IN token from the host, and it currently has no data to send, how should it response
to the IN token? Send a zero-length packet or send nothing?

Thanks.
