I have connected my CG Pro 9S12 to the laptop via the usb cable. But when I run the CG Pro software, I got the error message “Device is disconnected” and “Device is not connected”. Is this because I didn’t connect the device to my car?

CG Pro doesn’t come with a 12V power supply, you need to get one.
First plug in 12V power supply
Then connect the CG Pro to the computer via the USB cable
Finally, open CG Pro software to operate.
