How does USB reach the high speed of theory

Hello,

      I use IMX28's USB0 as a custom HID device. At the initial time, the maximum speed of transmission reaches 900KB/S. After modifying the register USBCMD's ITC, the interrupt response time is changed to the immediate response. Now the speed can reach 2MB/S, but the speed is still no more than 8MB/S. How should we do it, and continue to improve the speed?
