The HIDConnectionEvent interface of the WebHID API represents HID connection events, and is the event type passed to HID.onconnect and HID.ondisconnect when an input report is received.

Event HIDConnectionEvent


HIDConnectionEvent() Experimental

Returns a new HIDConnectionEvent object. Typically this constructor is not used as events are created when an input report is received.

Instance properties

This interface also inherits properties from Event.

HIDConnectionEvent.device Read only Experimental

Returns the HIDDevice instance representing the device associated with the connection event.


The following example registers event listeners for connect and disconnect events, then prints the HIDDevice.productName to the console.

navigator.hid.addEventListener("connect", ({ device }) => {
  console.log(`HID connected: ${device.productName}`);

navigator.hid.addEventListener("disconnect", ({ device }) => {
  console.log(`HID disconnected: ${device.productName}`);
