virtual address is different with physical address in some CPU

Hi,I had transplant usbx to my platform. When I used mass storage class with EHCI to read or write U disk, I test the speed but it was very slowly. When the HCD had create qH and qTD, the EHC started to transfer a BULK packet, but the time from it to trigger a USBINT interrupt, it expended some hundred milliseconds or more. I don't understand. Whether the memory of data structures that controled by HC is special or has some characteristic, whether there is something that i don't configure or notify well.

If can, please give some advices. Thanks very much.
