The productName read-only property of the HIDDevice interface returns the product name of the connected HID device.

A string.

The following example retrieves devices with HID.getDevices() and logs the value of productName to the console.

document.addEventListener("DOMContentLoaded", async () => {
  let devices = await navigator.hid.getDevices();
  devices.forEach((device) => {
    console.log(`HID: ${device.productName}`);
  });
});
