#### Event: 'select-usb-device'
Returns:
* `event` Event
* `details` Object
* `deviceList` [USBDevice[]](structures/usb-device.md)
* `frame` [WebFrameMain](web-frame-main.md)
* `callback` Function
* `deviceId` string (optional)
Emitted when a USB device needs to be selected when a call to
`navigator.usb.requestDevice` is made. `callback` should be called with
`deviceId` to be selected; passing no arguments to `callback` will
cancel the request. Additionally, permissioning on `navigator.usb` can
be further managed by using [ses.setPermissionCheckHandler(handler)](#sessetpermissioncheckhandlerhandler)
and [ses.setDevicePermissionHandler(handler)`](#sessetdevicepermissionhandlerhandler).
```javascript
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow()
win.webContents.session.setPermissionCheckHandler((webContents, permission, requestingOrigin, details) => {
if (permission === 'usb') {
// Add logic here to determine if permission should be given to allow USB selection
return true
}
return false
})
// Optionally, retrieve previously persisted devices from a persistent store (fetchGrantedDevices needs to be implemented by developer to fetch persisted permissions)
const grantedDevices = fetchGrantedDevices()
win.webContents.session.setDevicePermissionHandler((details) => {
if (new URL(details.origin).hostname === 'some-host' && details.deviceType === 'usb') {
if (details.device.vendorId === 123 && details.device.productId === 345) {
// Always allow this type of device (this allows skipping the call to `navigator.usb.requestDevice` first)
return true
}
// Search through the list of devices that have previously been granted permission
return grantedDevices.some((grantedDevice) => {
return grantedDevice.vendorId === details.device.vendorId &&
grantedDevice.productId === details.device.productId &&
grantedDevice.serialNumber && grantedDevice.serialNumber === details.device.serialNumber
})
}
return false
})
win.webContents.session.on('select-usb-device', (event, details, callback) => {
event.preventDefault()
const selectedDevice = details.deviceList.find((device) => {
return device.vendorId === '9025' && device.productId === '67'
})
if (selectedDevice) {
// Optionally, add this to the persisted devices (updateGrantedDevices needs to be implemented by developer to persist permissions)
grantedDevices.push(selectedDevice)
updateGrantedDevices(grantedDevices)
}

})
})

#### Event: 'usb-device-added'
Returns:
* `event` Event
* `details` Object
* `device` [USBDevice](structures/usb-device.md)
* `frame` [WebFrameMain](web-frame-main.md)
Emitted after `navigator.usb.requestDevice` has been called and
`select-usb-device` has fired if a new device becomes available before
the callback from `select-usb-device` is called. This event is intended for
use when using a UI to ask users to pick a device so that the UI can be updated
with the newly added device.
#### Event: 'usb-device-removed'
Returns:
* `event` Event
* `details` Object
* `device` [USBDevice](structures/usb-device.md)
* `frame` [WebFrameMain](web-frame-main.md)
Emitted after `navigator.usb.requestDevice` has been called and
`select-usb-device` has fired if a device has been removed before the callback
from `select-usb-device` is called. This event is intended for use when using
a UI to ask users to pick a device so that the UI can be updated to remove the
specified device.
#### Event: 'usb-device-revoked'
Returns:
* `event` Event
* `details` Object
* `device` [USBDevice[]](structures/usb-device.md)
* `origin` string (optional) - The origin that the device has been revoked from.
Emitted after `USBDevice.forget()` has been called. This event can be used
to help maintain persistent storage of permissions when
`setDevicePermissionHandler` is used.
### Instance Methods

* `webContents` ([WebContents](web-contents.md) | null) - WebContents checking the permission. Please note that if the request comes from a subframe you should use `requestingUrl` to check the request origin. All cross origin sub frames making permission checks will pass a `null` webContents to this handler, while certain other permission checks such as `notifications` checks will always pass `null`. You should use `embeddingOrigin` and `requestingOrigin` to determine what origin the owning frame and the requesting frame are on respectively.
