Cannot access cameras USB Camera through Camera2 API

[PYBurosse]

Hello,

I am currently trying to build an app using visio, that is meant to run on a qualcomm android board. This OS is modified so that USB cameras are recognised by the Camera2 API, and that works fine with our others apps, so I dont believe I need to use the UVCCamera tutorial (https://docs.mapbox.com/help/tutorials/android-vision-sdk-usb-camera/). But when I try to run the one I build using the Vision SDK, or the mapbox-vision-teaser app, I get that same error :

It seems to me that VisionManager cannot access the camera, but i can't figure out why.

I don't know if that matter, but the app should be running on an Android automotive. When I build it on my phone, it works fine, but it has embedded cameras...
