HID USB,Bus Hound能收到数据，VC写的代码则一直阻塞

stm32f103的板子，要作为一个USB HID设备，将CUSTOM_HID项目修改了下，USB初始化完毕之后，不断向上位机发送数据：

u8 b[2] = {0};
while (1)
  {
   for (i = 0; i < 1000000; i++);
   b[1]++;
   UserToPMABufferCopy(&b, GetEPTxAddr(ENDP1), 2);
   SetEPTxCount(ENDP1, 2);
   SetEPTxValid(ENDP1);
  }

利用Bus Hound，能收到不断从stm32板子上发送上来的数据。

利用2KDDK，写了个USB设备的读取程序，能够枚举到USB设备，然后也能CreateFile打开，但是ReadFile的时候，一直就阻塞在那边。
这个读取的程序是我以前一个项目中抽出来的，以前一直用，应该是没有问题的。现在想是不是stm32板子上的USB HID配置不对，摸不着头脑 -_-!!

下面是stm32上的配置数组，高手请教了。。
