请问CH554G如何驱动XR21V1410芯片？

现在打算用CH554G做一个转接板，需要驱动XR21V1410芯片，找了倒程只有PL2302,CH340,CP2012的，不知道XR21V1410如何设置串口参数，是否可以提供解决方法？怎么组SETUP包，应该按什么样的顺序发送SETUP包？

如果是通过USB通讯的话，可以先接入电脑，通过电脑端USB抓包工具看一下操作流程。然后单片机模拟这个流程操作USB设备。

有没有什么文档可以说明这个过程如何分析操作的？现在用Bus Hound 抓包也不会看，有点头大

自己搞定了，因为自己的需求很简单，就是透传USB口和串口的数据，9600的波特率，停止位-1，奇偶校验-无，数据位-8。
还是看芯片的规格书，不需要插电脑上用USB数据抓包，用的原厂的例程，然后找到芯片的PID,VID，再按着例程的驱动CH340的方式来写匹配PID,VID,匹配上了后设置波特率，根据规格书来组SETUP包，其中发SETUP包的时候，刚开始用FOR循环发会有问题，后面改成一条条好就可以，花了很多时间来了解USB的相关内容，其实例程已经做好了很多前面的工作，只要自己组SETUP包，然后发送就可以正常运行起来了。参考了这个文章的思路http://www.wch.cn/bbs/thread-72287-1.html
下面是程序改动的地方：
USBHOST_IF.C文件
#define XR21V1410_VENDOR_ID0X04E2 //ADD by sean增加VID
#define XR21V1410_PRODUCT_ID 0X1410 //ADD by sean增加PID


const UINT16 XR21V1410_ID_Table[]={XR21V1410_VENDOR_ID,XR21V1410_PRODUCT_ID,}; //ADD by sean 增加表


//配置XR21V1410波特率 ,成功返回0
UINT8 XR21V1410_Baud_Config(UINT32 baud)
{
UINT8 s=0;
//UINT16 i=0,j=0;
