BTW, why does Intel call it a "rate-matching" hub? In what sense does it match rates? Do they mean that it can match the high-speed upstream connection to the host controller with the downstream connection to a full- or low-speed device? And if they do, why mention it specially? The USB-2.0 specification requires all high-speed hubs to be capable of doing this.
