DM6446 usb issues

Dear all,

        We meet a problem while working with dm6446 and usb camera.  The camera can only transfer small packets(under 1024),  for dm6446 do not support high-bandwidth ISOC transfer.

        So the usb bandwidth with dm6446 can only up to 4.5MBps. But according to the datesheet, dm6446 support high-speed usb which can run up to 480Mbps.

        The linux kernel is 2.6.32.

        Who know how to solve the problem?
