Error Opening 2 HD Cameras Together

Python
,
1

Hello i tried to run 2 HD Cameras (Logitech C310) together using this code:

import cv2

def main():
    # Open the first webcam (usually index 0)
    cap1 = cv2.VideoCapture(0,cv2.CAP_DSHOW)  # Use dshow backend
    if not cap1.isOpened():
        print("Error: Could not open webcam 1")
        return

    # Open the second webcam (usually index 1)
    cap2 = cv2.VideoCapture(1,cv2.CAP_DSHOW)  # Use dshow backend
    if not cap2.isOpened():
        print("Error: Could not open webcam 2")
        cap1.release()  # Release the first webcam
        return
    print("masuk")

    # Set MJPG as FourCC for both webcams
    cap1.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter_fourcc(*'MJPG'))
    cap2.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter_fourcc(*'MJPG'))
    # cap1.set(cv2.CAP_PROP_FRAME_WIDTH, 640)
    # cap1.set(cv2.CAP_PROP_FRAME_HEIGHT, 480)

    # cap2.set(cv2.CAP_PROP_FRAME_WIDTH, 640)
    # cap2.set(cv2.CAP_PROP_FRAME_HEIGHT, 480)
    while True:
        # Read frames from the webcams
        ret1, frame1 = cap1.read()
        ret2, frame2 = cap2.read()

        if not ret1 or not ret2:
            print("Error: Could not read frames from webcams")
            break

        # Display the frames
        cv2.imshow("Webcam 1", frame1)
        cv2.imshow("Webcam 2", frame2)

        # Exit loop when 'q' is pressed
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

    # Release the webcams and close OpenCV windows
    cap1.release()
    cap2.release()
    cv2.destroyAllWindows()

if __name__ == "__main__":
    main()

After i run this code, i always get the same error:

Error: Could not open webcam 2

I already tried to change the USB port and use USB 3.0, but there was always an error in the webcam 2. This program works when I change the VideoCapture(0) device with another camera that is not HD and use the MSMF backend for VideoCapture (0). But when this camera uses the DSHOW event, if it uses a non-HD camera, it will error. But when I use this scheme with two HD cameras, this program will give me errors in the above.
