    DX79SI + USB3.0 device from Cypress

    Fx

      Hi all,

       

      we've got problems when connecting a Cypress USB 3.0 based device. The enumeration is broken when connecting a device. Thus it will not be recognized by the MB. When adding an external HUB between the device and the MB everything works.

       

      Cypress told us, that this problem is 'Spread Spectrum' related due to shifting the PCI-clock.

       

      Any thoughts?

       

      Regards,

      Franz
