FX2 has lesser bandwidth if using it on a USB3.0 host controller

Hi,

 

does anybody have any experiences while using FX2 (USB2.0 HS) chip on a USB3.0 Hostconrtoller (e. g. Intel onboard or Renesas PCIx Card)? We see, that the bandwidth on a USB2.0 Hostcontroller is higher than at a USB3.0 Hostcontroller. How can that be???

regards,

lumpi

 Usually we have seen that the throughput on FX2LP is better on USB 3.0 host.
