The vendorId read-only property of the HIDDevice interface returns the vendor ID of the connected HID device. This identifies the vendor of the device.

An integer. If the device has no vendor ID, or the vendor ID cannot be accessed this will return 0.

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

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