为什么CY68013A的驱动只能收到00和01的价值？

嗨，我遇到了一个奇怪的问题：我用Visual Studio写了一个小软件，在这个软件中，我读了桌面文件并把它发送到CY68013A芯片。开始时，转移是正确的。但是经过几次转移，我只能收到00和01的价值，无论发送什么。我想这可能是司机的问题，你有什么办法解决吗？
谢谢！

  Hi, I met a strange problem: I wrote a little software by visual studio, in this software, I read desk file and send it into cy68013a chip. In the beginning, transfer is right. But after several transfer, I can only receive 00 and 01 value, whatever to send. I think it may be the driver problem, do you have any idea to solve it?

Thanks a lot!
