Get all connected devices

Web
Node.js

After the user has granted permission to access the device, the next time the user visits the page, the Web app can access the device directly without asking for permission again.

Previously, we have disabled the permission system in usb package's WebUSB implementation, so it will return all devices that are currently connected.

WebUSB USB#getDevices method can be used to get all connected devices (that the user has granted permission to access). However, it might return non-ADB devices as well.

To only get ADB devices, AdbDaemonWebUsbDeviceManager#getDevices method also accepts a filters option, to only return devices that match the specified criteria.

declare class AdbDaemonWebUsbDeviceManager {
  getDevices(filters?: AdbDeviceFilter[]): Promise<AdbDaemonWebUsbDevice[]>;
}

note

See Device filter for more information about how does the filter work and how to define a filter.

The filters option defaults to [ADB_DEFAULT_DEVICE_FILTER], which matches the ADB interface. Unless your ADB devices uses a different identifier, or you want to select a specific device, you can just call AdbDaemonWebUsbDeviceManager#getDevices without any arguments:

info

Some lazy manufacturers use the same serialNumber for all devices. So even if serialNumber is specified, it's still possible that multiple devices will be returned.

JavaScript
TypeScript

const devices = await Manager.getDevices();
if (!devices.length) {
  alert("No device connected");
  return;
}

const device = devices[0];

import { AdbDaemonWebUsbDevice } from "@yume-chan/adb-daemon-webusb";

const devices: AdbDaemonWebUsbDevice[] = await Manager.getDevices();
if (!devices.length) {
  alert("No device connected");
  return;
}

const device: AdbDaemonWebUsbDevice = devices[0];

Examples

To select a specific manufacturer and model:

JavaScript
TypeScript

import { ADB_DEFAULT_DEVICE_FILTER } from "@yume-chan/adb-daemon-webusb";

const devices = await Manager.getDevices([
  {
    ...ADB_DEFAULT_DEVICE_FILTER,
    vendorId: 0x18d1,
    productId: 0x4ee2,
  },
]);

import { AdbDaemonWebUsbDevice, ADB_DEFAULT_DEVICE_FILTER } from "@yume-chan/adb-daemon-webusb";

const devices: AdbDaemonWebUsbDevice[] = await Manager.getDevices([
  {
    ...ADB_DEFAULT_DEVICE_FILTER,
    vendorId: 0x18d1,
    productId: 0x4ee2,
  },
]);

To allow multiple manufacturers/models:

JavaScript
TypeScript

import { ADB_DEFAULT_DEVICE_FILTER } from "@yume-chan/adb-daemon-webusb";

const device = await Manager.getDevices([
  {
    ...ADB_DEFAULT_DEVICE_FILTER,
    vendorId: 0x18d1,
    productId: 0x4ee2,
  },
  {
    ...ADB_DEFAULT_DEVICE_FILTER,
    vendorId: 0x04e8,
    productId: 0x6860,
  },
]);

import { AdbDaemonWebUsbDevice, ADB_DEFAULT_DEVICE_FILTER } from "@yume-chan/adb-daemon-webusb";

const device: AdbDaemonWebUsbDevice | undefined = await Manager.getDevices([
  {
    ...ADB_DEFAULT_DEVICE_FILTER,
    vendorId: 0x18d1,
    productId: 0x4ee2,
  },
  {
    ...ADB_DEFAULT_DEVICE_FILTER,
    vendorId: 0x04e8,
    productId: 0x6860,
  },
]);
