我正在尝试创建一个.NET Maui应用程序，该应用程序可以从通过USB（RS-232仿真）连接的设备（条形码阅读器）读取数据。我获取设备，强制权限请求，但应用程序继续，而不等待授予权限的结果。请不要有你的成功的解决方案可用？不幸的是，我在.NET Maui文档中找不到任何东西。
这是我的代码，基于[https：//stackoverflow.com/questions/73534644/how-to-write-raw-data-to-usb-connected-device-using-net-maui]中的示例：

Activity act = Platform.CurrentActivity;
UsbManager manager = (UsbManager)act.GetSystemService(Context.UsbService);
IDictionary<string, UsbDevice> devicesDictionary = manager.DeviceList;
UsbDevice dvc = _usbDevice; // I find _usbDevice successfully

string ACTION_USB_PERMISSION = "com.MauiAndroidSerialPort.USB_PERMISSION";
var interf = dvc.GetInterface(1);
var outEndpoint = interf.GetEndpoint(1);
PendingIntent mPermissionIntent = PendingIntent.GetBroadcast(act, 0, new Intent(ACTION_USB_PERMISSION), PendingIntentFlags.Immutable);

IntentFilter filter = new IntentFilter(ACTION_USB_PERMISSION);
if (manager.HasPermission(dvc) == false)
    manager.RequestPermission(dvc, mPermissionIntent);
//Here I would need the result of enabling permissions

var deviceConnection = manager.OpenDevice(dvc);

if (deviceConnection != null)
    deviceConnection.ClaimInterface(interf, true).ToString();
