Both UVC & UAC getting start doesn't want to compile for ESP32-S3

我也遇到了同样的问题：

undefined reference to `mps_limits_default'
undefined reference to `mps_limits_bias_rx'

我的板子是ESP32-S3-LCD-EV-Board，在usb->start()这个函数调用的时候出现了这个问题
奇怪的是我发现这个问题是在将arduino的开发板管理器中将esp32板子的版本号升级到v3.0.2之后出现的这个问题，之前我用v2.x跑的时候是没问题的，可能是升级后改变了函数接口

@alibukharai @Lzw655 ,抱歉以这样的方式at你们，但我真的很需要这个头文件，

[joyel24]

I'll do the same test later with the UVC & UAC getting start example with the same module and same usb peripheral to see how it works now...

我使用的也是 ESP32-S3-LCD-EV-Board v1.5，依旧不知道这个库怎么用，方便把你的 demo 贴上来吗

[jiesou]

完全使用
https://github.com/esp-arduino-libs/ESP32_USB_Stream/blob/master/examples/GettingStartUVC/GettingStartUVC.ino
也是一样的错误
