According to the document, If Target API>= 28, you need to grant Manifest.permission.CAMERA permission, after that you will see the permission dialog.

In Android 10, except for the version with internal version number R30, there is a bug that the uvc camera cannot obtain USB device permissions, and there is no permission application pop-up window.
