Android OTG Detect App

[Pavlex4]

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 mHashMap = new HashMap();
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.LEN
