    cy68013a winxp bulk in transfer

      Hi, I am trying to use CY7C68013A to transfer data from Sensor to PC. 


      I use EP2 on slave FIFO mode.The FIFO is 512x4.My PC is programmed by VC++ 2012, using the function BeginDataXfer,WaitForXfer and FinishDataXfer to receive 1 frame per cycle.My driver is cyusb3.sys.


      When my OS is win7,i can get data.


      But in XP,when the Xfer length is lager than 3840000bytes,the system die,and i have to Forced shutdown.and when length is 3520000 or less,it can get data.


      Then i use USB Control Center:Transfer Data-IN,it is the same.The WIN7 is OK,but XP die...(when Bytes to Transfer is 3840000)


      So,what is the problem?OS?
