+<uses-permission android:name="android.permission.USB_HOST" />
+<uses-feature android:name="android.hardware.usb.host" android:required="true" />
+```
+
+#### b. Accessing USB Camera:
+You can use the [UVCCamera](https://github.com/saki4510t/UVCCamera) library. 
+Here's a basic way to integrate it:
+
+1. Clone the UVCCamera repository.
+2. Import the library into your Unity project.
+3. Create a bridge class in Unity to interface with the library.
+
+### 3. Display Camera Feed in VR:
+
+#### a. Create a 3D Plane in Unity:
+- In the Unity hierarchy, right-click and create a 3D Plane.
+- This will be used to display the camera feed.
+
+#### b. Display Camera Feed:
+```csharp
+public RawImage displayImage; // Drag your RawImage component here in the inspector
+
+void UpdateCameraFeed(Texture cameraTexture)
+{
+    displayImage.texture = cameraTexture;
+}
+```
+
+### 4. User Interface & Controls:
+

+- Use Oculus Integration's `OVRInputModule` to make the UI interactive in VR.
+
+#### b. VR Controls:
+- Use the `OVRInput` class from Oculus Integration to detect button presses and controller movements.
+
+### 5. Testing:
+
+- Build and run your Unity project for the Android platform.
+- Wear your Quest 2 and test the app's functionality.
+
+### 6. Deployment:
+
+- Follow Oculus' [submission guidelines](https://developer.oculus.com/distribute/latest/concepts/publish-submission-guidelines/) to submit your app to the Oculus Store.
+
+### 7. Considerations:
+
+- Regularly test with different USB OTG cameras to ensure broad compatibility.
+- Monitor battery usage and optimize as necessary.
