## USB Stream Component

`usb_stream` is an USB `UVC` + `UAC` host driver for ESP32-S2/ESP32-S3, which supports read/write/control multimedia streaming from usb device. For example, at most one UVC + one Microphone + one Speaker streaming can be supported at the same time.

Features:

1. Support video stream through UVC Stream interface, support both isochronous and bulk mode
2. Support microphone stream and speaker stream through the UAC Stream interface
3. Support volume, mute and other features control through the UAC Control interface
4. Support stream separately suspend and resume

> Note: For ESP-IDF V5.3.3 and above, if you enable UVC, please also enable `Bias IN` in `Component config → USB-OTG → Hardware FIFO size biasing`.

### Q&A

Q1. I encountered the following problems when using the package manager

```
Executing action: create-project-from-example
CMakeLists.txt not found in project directory /home/username
```

A1. This is because an older version package manager was used, please run `pip install -U idf-component-manager` in ESP-IDF environment to update.
