pic32_mzef_curiosity_v2：仅USB设备（音频＆＃x2B; CDC）不起作用
这是我在USB环境中的第一次，因此，任何意见都得到了高度赞赏。
我的设置：
-pic32 me好奇心v2板 + AK4954编解码器模块，使用mikro Bus 2使用mplab x 5v5 iDe在Harmony 3
-My当前项目代码/示例代码/ WireShark数据 下https://artagroup-my.sharepoint.com/:f:/g/personal/gokulnath_arcot-ramanandan_comufrance_com/emj0e83migjktbb1huigtnybaqs43xvfnxvfncvfncq qcq0xxd7m9
ztta微芯片音频＆amp; CDC示例是功能性
所需结果：（仅USB设备模式）
我想模仿USB耳机（从Android电话上播放YT视频的音频） + CDC（自定义数据发送到Android上的Serial USB终端应用程序按按钮按下）
我的进度：
我使用了默认的微芯片功能音频示例＆amp;将CDC示例集成到其中。 我的USB复合设备正确列举了我的PC（设备管理器）＆amp;然后，
“This device cannot start. (Code 10)” on windows I use a software named “UsbTreeView” I checked it and It’s telling me like this：
----------------- Device Qualifier Descriptor -----------------
Error : ERROR_GEN_FAILURE
如果我很好地了解USB概念 - ＆gt; IAD（接口 协会描述符）也准确地声明了。但是我有一个 对配置描述符的怀疑。
在Windows中，它显示了COM端口（CDC正确列举了 音频处于错误状态），但是当我尝试使用putty时，没有数据是 流过，但我可以看到董事会发送的数据 按钮按下Wireshark。
我还将Wireshark日志附加了，就像按下按钮时，我可以看到从设备发送到主机的中断 +数据。 （但是带有此错误：irp usbd_status：usbd_status_canceled（0xc0010000））
然后，我将其连接到我的Android Phone＆amp;音频功能性＆amp; CDC终端站“控制转移失败”
我还将其连接到Ubuntu PC＆amp;音频功能正常 ＆amp; CDC终端TTYACM0“终端打开失败” App“屏幕”

请让我知道可能的解决方案＆amp;我应该更多地关注哪个领域？
感谢您的时间。我真的很感谢它
有美好的一天
This is the first time for me in a USB environment hence any input is highly appreciated.
My Setup:
-Pic32 ME EF curiosity v2 board + AK4954 Codec Module attached to mikro Bus 2 using Mplab x 5V5 IDE under Harmony 3
-My current project code/ example codes / Wireshark data WIP here
-default microchip audio & cdc examples are functional
Desired result:(USB Device mode only)
I would like to emulate USB headphones (Audio playing from YT video on android phone) + CDC (custom data sent to serial USB terminal app on Android upon button press)
My progress:
I've used the default Microchip functional audio example & integrated the CDC example into it.
My USB composite device is enumerated correctly into my PC (device manager) & then I'm receiving
“This device cannot start. (Code 10)” on windows I use a software named “UsbTreeView” I checked it and It’s telling me like this：
----------------- Device Qualifier Descriptor -----------------
Error : ERROR_GEN_FAILURE
if I’ve understood the USB concept well -> The IAD(Interface
association descriptor) is also declared accurately. but I'm having a
doubt on configuration descriptors.
In windows, it shows The com port(CDC is enumerated correctly but the
audio is in an error state) but when I tried using putty no data is
flowing through but I could see the data sent from the board on
Wireshark upon button press.
I've also attached the Wireshark log as when I press the button I can see the interrupt + data sent from the device to the host. (but with this error:IRP USBD_STATUS: USBD_STATUS_CANCELED (0xc0010000))
I then connected this to my android phone & the audio is functional &
CDC terminal station "control transfer failed"
I also connected this to UBUNTU PC & the audio is functional properly
& CDC terminal TTYACM0 "Terminal open failed " by the app "Screen"
