Irregular movements of the left and right trackballs/mice in Unity

Unity Engine
1

Currently, I am dealing with the irregular movements (video) of the left and right trackballs/mice which are based on the x and y axis values from corresponding trackballs/mice.

These are the methods that are responsible for the movements

public void Update()
    {
        while (inputQueue.TryDequeue(out var val))
        {
            if (val.Header.Type == RawInputType.Mouse && val.Header.Device.ToInt32() == leftTrackballDeviceID)
            {
                float mouseX = val.Data.Mouse.LastX;
                float mouseZ = -val.Data.Mouse.LastY;
                UpdateCursorPosition(leftCursor, mouseX, mouseZ);
            }
            else if (val.Header.Type == RawInputType.Mouse && val.Header.Device.ToInt32() == rightTrackballDeviceID)
            {
                float mouseX = val.Data.Mouse.LastX;
                float mouseZ = -val.Data.Mouse.LastY;
                UpdateCursorPosition(rightCursor, mouseX, mouseZ);
                Debug.Log("mouseX: " + mouseX + " mouseZ: " + mouseZ);
            }
        }

    }

    private void UpdateCursorPosition(GameObject cursor, float x, float z) 
    {
        Vector3 currentPosition = cursor.transform.position;
        currentPosition.x += x * cursorSpeed * Time.deltaTime;
        currentPosition.z += z * cursorSpeed * Time.deltaTime; 
        cursor.transform.position = currentPosition;
    }

Currently, I am don’t know what is happeing with my code. I want the cursors (red moving circles in the video) to just move over the keyboard buttons (such that it will always intersect a button when moving).I am working on a 3D VR project in Unity.Please help me to figure out the problem.

Use debug, and se what it says and shows.

Chances are, issue may ne on hardware side, but at this point I just guess.
Vid doesn’t work.

And that thread belongs to scripting forum.
