华为UAC耳机 概述

本人手中有一个华为的TYPE-C耳机，其实是一个复合设备（usbccgp.sys）。这个复合设备总共有三个分设备，分别为HeadPhone(耳机)，Microphone(麦克风)和一个自定义的HID设备。

在设备管理器中设备树关系如下：

设备的硬件ID如下:

• USB\VID_12D1&PID_3A07&REV_0024(USB Composite Device)
  • USB\VID_12D1&PID_3A07&REV_0024&MI_00(HUAWEI USB-C HEADSET)
    • MMDEVAPI\AudioEndpoints(耳机 (HUAWEI USB-C HEADSET))
    • MMDEVAPI\AudioEndpoints(麦克风 (HUAWEI USB-C HEADSET))
  • USB\VID_12D1&PID_3A07&REV_0024&MI_03(USB 输入设备)
    • HID\VID_12D1&PID_3A07&REV_0024&MI_03(人体学输入设备)

从硬件ID上分析可知：驱动从接口0开始的是UAC复合设备，一般情况下0接口是UAC的控制，1接口是UAC音频流，后续可能还有音频流如接口2。接口3是用于HID的复合设备。

使用UsbTreeView.exe工具显示的设备信息如下：
