在CH582的EVT包USB设备例程中，已有端点0~3的全部代码。端点4~7在手册中有描述，不过在例程中没有给出。
在端点0~7中，端点0与端点4与众不同。端点0只拥有64字节DMA缓存。这是符合USB协议标准的。作为USB设备都要默认支持的端点，USB协议要求设备的端点0是双向通信的；而其他端点是超级加倍，IN和OUT方向各有64字节的DMA缓存。
而端点4，其DMA地址是直接存放在64字节的端点0的DMA地址后的，配置了端点0的DMA地址后，就不必再次配置端点4的DMA。
原因未知，像是贴地砖时，用半块地砖填补到缝隙中，尽可能利用空间，不能浪费（把端点4的DMA区域塞到了端点0后面）；后续建筑扩建，在新地方继续铺整块地砖（端点5~7都独立的DMA缓存）。
不过这也带来一些麻烦，有更多的寄存器需要照顾。部分例程里已经配置好了，不必再关注端点4的配置。
以下是作为USB键鼠，在端点4、端点7中上传报表描述符的参考代码。
