    Hi Brian,

    I double checked with customer, that what they are seeking for is this functionality that the hub can change the upstream & downstream directions.

    Normal use case, this IC act as the HUB, and the host is the host, other four ports are peripherals.

    But for debugging or updating scenario, they will use the external debugger equipment to control the original host, then the hub need change the stream directions.

    Like Microchip, USB2534, this device has one port that can act automatically as the required stream directions.

    Does TI have solution support this? Or if single IC cannot support, Do we have system solution support this?

    BRs,

    Marsh
