您好，我使用了SlaveFifoSync的32bit模式例程，现在我想在其中添加一个HID的设备（鼠标），程序见附件，我参照了Can EZ-USB FX3 enumerate serial devices and video and video devices at the same time? 中的内容，添加了HID相关的描述符，添加了hid设备的端口配置和DMA通道配置以及hid的线程。但是HID的枚举是失败的（设备管理器中没有出现这个设备），debug中没有print错误，并且原来的Cypress FX3 USB StreamerExample Device的设备也出现了叹号，如果把HID的相关内容删去Cypress FX3 USB StreamerExample Device是可以正常使用的。我slaveFifo采用的端口是0X01和0X81，hid采用的端口是0X87。
请问我该如何修改程序？
我按照您上面的链接进行了描述符的修改，但是还是没有枚举成功
如果对FX3更新驱动的话，会显示“windows无法安装FX3”，可能是我的USB描述符还是有问题，您是否能帮我看下？
下面我贴出了CyFxUSBSSConfigDscr的描述符，slaveFIFO分别使用0x81和0x01端点，HID使用0X84端点
