4.2 Hot Plug Support
Hot Plug insertion and removal are supported in the presence of a proper
connector and appropriate operating system (OS) support as described in the
SATA 2.6 specification. This product supports Asynchronous Signal Recovery
and will issue an unsolicited COMINIT when first mated with a powered
connector to guarantee reliable detection by a host system without hardware
device detection.
