我把我的代码贴出来，大伙看看，有什么问题？
void Joystick_Reset(void)
{
/* Set Joystick_DEVICE as not configured */
pInformation->Current_Configuration = 0;
pInformation->Current_Interface = 0;/*the default Interface*/
/* Current Feature initialization */
pInformation->Current_Feature = Joystick_ConfigDescriptor[7];

SetEPRxValid(ENDP0);
/* Initialize Endpoint 1 */
SetEPType(ENDP1, EP_INTERRUPT);
SetEPTxAddr(ENDP1, ENDP1_TXADDR);
SetEPTxCount(ENDP1, 5);
//SetEPRxStatus(ENDP1, EP_RX_DIS);
SetEPTxStatus(ENDP1, EP_TX_NAK);
/* Initialize Endpoint Out 1 */
SetEPRxAddr(ENDP1, ENDP1_RXADDR); //设置接收数据的地址

/* Initialize Endpoint 2 */
SetEPType(ENDP2, EP_INTERRUPT);
SetEPTxAddr(ENDP2, ENDP2_TXADDR);
SetEPTxCount(ENDP2, 5);
//SetEPRxStatus(ENDP1, EP_RX_DIS);
SetEPTxStatus(ENDP2, EP_TX_NAK);
//拷贝用户数据到端点2的发送缓存区
