    CY7C65620 - unknown device on Downstream Port

    yeti89-89_2288591

      I assembled a PCB based on the Schematic:

      http://www.cypress.com/documentation/reference-designs/cy4606-ez-usb-hx2lp-high-speed-low-power-usb-20-compliant-4-port-…

      My scheme in the attachment (1).

       

      I write a standard file 2_port.iic in the EEPROM with the program "Blaster".

       

      The hub is defined as a universal USB hub in the device manager. But connected to the Downstream Ports flash cards are defined as an unknown device!

       

      Help me please

      Why the hub does not work correctly?
