HidApiError { message: "No HID devices with requested VID/PID found in the system." }

I ran example code

fn main() {
    let api = hidapi::HidApi::new().unwrap();
    // Print out information about all connected devices
    for device in api.device_list() {
        println!("{:#?}", device);
    }

    // Connect to device using its VID and PID
    let (VID, PID) = (0x0123, 0x3456);
    let device = api.open(VID, PID).unwrap();

    // Read data from device
    let mut buf = [0u8; 8];
    let res = device.read(&mut buf[..]).unwrap();
    println!("Read: {:?}", &buf[..res]);

    // Write data to device
    let buf = [0u8, 1, 2, 3, 4];
    let res = device.write(&buf).unwrap();
    println!("Wrote: {:?} byte(s)", res);
}

But I got an error.
