Android OTG Cable Detect

How to use app to detect when otg cable is plugged in and when it's plugged out? Is there intent for otg cable like this for usb devices: "android.hardware.usb.action.USB_DEVICE_ATTACHED"

I have created app like this but I only detects flash drive not otg cable:

public class MainActivity extends AppCompatActivity {

private TextView mInfo;
private Logger mLogger;
private HashMap<UsbDevice, UsbDataBinder> mHashMap = new HashMap<UsbDevice, UsbDataBinder>();
private UsbManager mUsbManager;
private PendingIntent mPermissionIntent;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mInfo = (TextView)findViewById(R.id.log);

    mLogger = new Logger(this);
    mLogger.setMode(Logger.MODE_TOAST);

    mUsbManager = (UsbManager) getSystemService(Context.USB_SERVICE);

    usbConnection();
}

private void usbConnection() {
    IntentFilter filter = new IntentFilter(UsbManager.ACTION_USB_DEVICE_ATTACHED);
    registerReceiver(mUsbAttachReceiver , filter);
    filter = new IntentFilter(UsbManager.ACTION_USB_DEVICE_DETACHED);
    registerReceiver(mUsbDetachReceiver , filter);

    mPermissionIntent = PendingIntent.getBroadcast(this, 0, new Intent(ACTION_USB_PERMISSION), 0);
    filter = new IntentFilter(ACTION_USB_PERMISSION);
    registerReceiver(mUsbReceiver, filter);

    showDevices();
}

protected void onDestroy() {
    super.onDestroy();
    unregisterReceiver(mUsbDetachReceiver);
    unregisterReceiver(mUsbAttachReceiver);
    unregisterReceiver(mUsbReceiver);
};

BroadcastReceiver mUsbDetachReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (UsbManager.ACTION_USB_DEVICE_DETACHED.equals(action)) {
            UsbDevice device = (UsbDevice)intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
            if (device != null) {
                // call your method that cleans up and closes communication with the device
                UsbDataBinder binder = mHashMap.get(device);
                if (binder != null) {
                    binder.onDestroy();
                    mHashMap.remove(device);
                    Toast.makeText(MainActivity.this, "Attached!", Toast.LENGTH_SHORT).show();
                }
            }
        }
    }
};

BroadcastReceiver mUsbAttachReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (UsbManager.ACTION_USB_DEVICE_ATTACHED.equals(action)) {
            showDevices();
            Toast.makeText(MainActivity.this, "Detached!", Toast.LENGTH_SHORT).show();
        }
    }
};

private static final String ACTION_USB_PERMISSION = "com.android.example.USB_PERMISSION";
private final BroadcastReceiver mUsbReceiver = new BroadcastReceiver() {

    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (ACTION_USB_PERMISSION.equals(action)) {
            synchronized (this) {
                UsbDevice device = (UsbDevice) intent
                        .getParcelableExtra(UsbManager.EXTRA_DEVICE);

                if (intent.getBooleanExtra(
                        UsbManager.EXTRA_PERMISSION_GRANTED, false)) {
                    if (device != null) {
                        // call method to set up device communication
                        UsbDataBinder binder = new UsbDataBinder(mUsbManager, device);
                        mHashMap.put(device, binder);
                        Toast.makeText(MainActivity.this, "Permission Granted!", Toast.LENGTH_SHORT).show();
                    }
                } else {
                    // Log.d(TAG, "permission denied for device " + device);
                }
            }
        }
    }
};

private void showDevices() {
    HashMap<String, UsbDevice> deviceList = mUsbManager.getDeviceList();
    Iterator<UsbDevice> deviceIterator = deviceList.values().iterator();
    while(deviceIterator.hasNext()){
        UsbDevice device = deviceIterator.next();
        mUsbManager.requestPermission(device, mPermissionIntent);
        //your code
        mLogger.log("usb", "name: " + device.getDeviceName() + ", " +
                "ID: " + device.getDeviceId());

        mInfo.append(device.getVendorId() + "\n");
    }
}

@Override

    // TODO Auto-generated method stub
    super.onResume();
