最近，我开始学习与Windows 10上的HID设备通信的知识。
但是我有几个问题。
根据Window的文档，HidD_SetOutputReport必须将ReportBuffer参数的第一个字节设置为报告ID或0x00。
由于设备的HID报告描述符已经声明了某些报告ID，所以当我使用HidD_setoutputreport而不是0x00时必须设置报告ID？
[当我将报表ID 0x80用作buf[0]时，例如：0x80 0x02 0x00 ....... 0x00（我的Capabilities.OutputReportByteLength是64）]
我的代码是ret = HidD_SetOutputReport(handle->device_handle, buf2, 65)
但是我总是这样发送数据（在Bus Hound上：
64 OUT 80 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00................ 4.1.000 00 00 00 00 00 00 00 00 00 00 00 00 0000 ................ 4.1.16
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................4.1.32
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................4.1.48
我认为它应该发送buf[1] to buf[64]而不是buf[0] to buf[63]，所以我尝试了ret = HidD_SetOutputReport(handle->device_handle, buf2, 64)，但结果是相同的。
这是我的INPUT和OUTPUT的HID报告描述符：

我无法真正评论Windows API（我从未使用过），但是我知道如果您在HID报告描述符中指定报告ID那么报告ID会占据数据包的第一个字节，其余的数据包中的内容是您的有效载荷，否则您的数据包中的所有内容都是没有发送REPORT_ID。在您的情况下，您的RD指定REPORT_ID，63字节的有效负载，因此我将指定长度为64，然后将第一个字节中的REPORT_ID。
将报告ID传输到终点，以便它可以知道解释每个报告
我已经检查了您的报告描述符，我可以提出一些调整措施，这些措施可能会减少未来的痛苦机会。
执行上述操作后，报告描述符的大小从203字节减少到133字节：
