    CY7C65642-28 - A request for the USB device descriptor failed.


      I have scoped every signal. The LED lights and oscillator is running until Windows 10 shuts down the hub after 3 seconds.

      USB downlinke is internally used, therefore no overcurrent protections. The power supply is stable.

      Part of the schematics attached.

      I am out of clues now - please give me some hints.
