A question about the interrupt endpoint

The article states....

To work around the long first-byte latency of USB, USBTMC devices automatically serial-poll themselves when they need to request service, and return both the SRQ line and the status byte in a single transmission. The advantage is that the host can receive the status byte without generating another USB transaction.

I do not understand what "serial-polling themselfs" could mean. I understood, that all transmissions are initiated by the host. Self-polling does not fit into this picture.
