External Camera Android sample fails to initialize on Quest due to OceanUSBManager singleton violation

[ReallyRad]

What happened?

The External Camera Android sample fails to render the live camera feed on Meta Quest devices. The application launches and OpenGL initializes correctly, and camera permissions are granted, but the preview remains a black screen.

The expected behavior is that the USB external camera stream initializes successfully and displays live video in the OpenGL view. Instead, the camera pipeline fails to initialize due to OceanUSBManager rejecting a second instance creation, which prevents the USB media pipeline from starting.

Steps to reproduce

Build and install com.meta.ocean.app.demo.media.externalcamera.android on a Meta Quest device
Launch the application
Grant USB/camera permissions when prompted
Observe that the app initializes but no camera image is rendered
