OpenHarmony版本支持USB接口摄像头吗？

我想使用 RK3568 平台，测试USB接口摄像头，用OpenHarmony版本自带的相机APP使用USB接口摄像头拍照。

请问下，OpenHarmory版本是否支持USB接口摄像头？如果支持的话，从哪个版本开始支持的？需要如何配置USB接口摄像头？相机APP能否直接调用USB接口摄像头？

在OpenHarmony 4.0 Release版本上测试，接入USB摄像头，串口打印如下日志：

日志提示usb device is not support，跟踪代码发现，USB只支持UAC（USB Audio Class），不支持UVC（USB Video Class），USB摄像头需要支持UVC，看来目前最新的OpenHarmony 4.0 Release版本不支持USB接口摄像头。

不知道Release版本什么时候可以支持USB摄像头？

可以直接调用，插入就可以。默认的系统相机app没有选择摄像头的功能。底层驱动和框架都是支持的

你好我也遇到了这个问题请问你解决了吗
