一般来说HID设备的报表在端点数量资源充裕的情况下都走中断端点上传，不会走控制端点即端点0上传，如果资源不足，可以利用端点0上传报表，USB协议中也是支持在端点0上传报表的。
以CH582为例，EVT中的键鼠复合例程中，键盘走端点1而鼠标走端点2上传报表，互不耽误。如果端点资源比较紧张，多个设备的报表比如键鼠的报表，可以走同一个端点上传，这时就要在同一个端点上传的数据中区分报表。区分方法也很简单，在报表开头再添加一个字节作为Report ID，比如说键盘和鼠标的Report ID分别设置为0x01和0x02，上传8字节键盘报表前再加个0x01即可。如果端点资源真的很紧张，其他端点都被占用了，又要跑CDC又要跑MIDI等等，那还有端点0可以使用。当然当端点资源很紧张时需要首先评估一下在端点0上报数据能不能满足稳定性要求，如果非要实现严格的1ms上传一个HID报表，还是建议留足资源。
默认例程代码中没有处理端点0上传的HID类请求，可以按参考下方代码。下方代码中新增了一个结构体记录各标志（ram紧张的话可以压缩压缩，按位标志），在主函数中处理报表的上传。PS：下列代码上传超过64字节的报表时有BUG，待修复。
