USB3控制端点OUT传输错误

由于在现有固件示例中需要响应转移（CyfFXYRQTJI2CYEEPROMYORD WORD），所以在PC应用软件中使用CyAPI库接口类中的“CyCuffEngestEndoPoT”的写（）函数进行传输，如下所示的代码已被AD德德。
GLAP0缓冲器〔0〕＝状态；状态＝CYU3PUBSENEDEND0DATA（1，GLAP0缓冲器）；
然而，超时错误（65）发生在CYU3PUBSENDEP0DATA数据中。我想知道是否有办法解决这个问题。

     以下为原文
  since response transfer is additionally needed from the existing firmware example
when Control OUT (CY_FX_RQT_I2C_EEPROM_WRITE) transfer using write() function of "CCyControlEndpoint"
among CyAPI library interface classes at PC application software occurs,
following code as shown below have been added.
                   glEp0Buffer[0] = status;
             status = CyU3PU***SendEP0Data(1, glEp0Buffer);
    However, timeout error (65) occured in CyU3PU***SendEP0Data.
I would like to know if there is some way to get this problem solved.
