SMSC USB2514 42

USB 2.0 High-Speed 4-Port Hub Controller

Datasheet

5.Moves device from suspended to active (if suspended).

6.Complies with Section 11.10 of the USB 2.0 Specification for behavior after completion of the reset sequence.

The Host then configures the Hub and the Hub’s downstream port devices in accordance with the USB Specification.
