この記事では、デバイス（RPiカメラとUSBカメラ）へのシンボリックリンクを作成しました。https://g0kao.wordpress.com/2013/08/08/usb-port-location-on-a-raspberry-pi/ところで機器を見つけられないことUSBができますね。
私はudevルールでproductid:vendorid=を使い続けます。0c45:636b
sudo nano /etc/udev/rules.d/10-local.rules
ACTION=="add", ATTRS{idVendor}=="0c45", ATTRS{idProduct}=="636b", SYMLINK+="SIDECAMERA"
しかし、これは役に立ちません。私のコード（私はopencvを使用しています）からカメラIDを提供する必要があります。
cv2.VideoCapture(0)有効ですがcv2.VideoCapture("dev/SIDECAMERA")効果的ではありません。
