    CYUSB3302 in embedded SS-PHY system

    sami.vaara_1752381

      I would like to share one SS-PHY (from SoC) with two SS USB device in embedded environment (no USB connectors at all). I am planning to use CYUSB3302, but I don't know how VBUS topology should be build to ensure functional SS links including power management. So in embedded environment I don't have VBUS as such, but do I need build some kind of "virtual" VBUS topology? Or can I make system work without any VBUS lines? All connectivity is SS, no USB2.0 PHYS involved.
