A USB hub is plugged into USB1.1 host and produces USB2.0 signal rate at the downstream ports?

Version 1
    Question: I want to design a USB hub that is plugged into USB1.1 host and produces USB2.0 signal rate at the downstream ports.

     

    Answer:

    Please note that the USB hub is just a repeater. If it is connected to a USB1.1 host, its downstream ports can only get USB1.1 signal rate. In order to get "USB2.0 capable" at the downstream ports, you need to have a USB2.0 hub connected to a USB2.0 host.
