    FPGA and PC problem



         I am now using USB3.0 to transfer data. The FPGA control squences is that  at first 500us FPGA do nothing to USB FX3 , and then transfer 128KBytes continuous data  to PC, and then it follow the cycles.


        But I found that the 500us void time pend my transfer. If I set the void time to 10us or less. The PC will get data without any problem. So why this problem happened.


        I increase the value of the waitforxfer() parameter. But the problem is still there.  thank  you.
