How to use the @ledgerhq/devices.identifyUSBProductId function in @ledgerhq/devices

constructor(device: HIDDevice) {
    super();
    this.device = device;
    this.deviceModel = identifyUSBProductId(device.productId);
    device.addEventListener("inputreport", this.onInputReport);
  }

device => {
        if (!unsubscribed) {

          observer.next({ type: "add", descriptor: device, deviceModel });
          observer.complete();
        }
      },
      error => {

devices.map(device => ({
              type: "add",
              descriptor: device,
              deviceModel: identifyUSBProductId(device.productId)
            }))
          )

const onAdd = device => {
