requestDevices very unreliable with newest Flutter

[iKK001]

Updating to Flutter 3.24.5 leads to new errors:

The biggest problem of your library seems the usbDevice.requestDevices([]) cmd !

It is very error prone.

Below is how I use it.

In debug-mode it leads to the error:

"TypeError: Instance of '_USBDevice': type '_USBDevice' is not a subtype of type 'UsbDevice?'"

In release-mode on my local machine it actually works !!

In release-mode on a remote server it leads to the error:

Null check operator used on a null value

Here is my code :
(again, it all happens at the step requestDevices !!!)

UsbDevice? _pairedDevice;
final UsbDevice usbDevice = UsbDevice();

Future<void> _connectToDevice() async {
  try {
    _pairedDevice = await usbDevice.requestDevices(
      [DeviceFilter(vendorId: 0x303a, productId: 0x1001)],
    );

    final deviceInfo = await usbDevice.getPairedDeviceInfo(_pairedDevice!);
    setState(() {
      _status = 'Connected to ${deviceInfo.productName}';
    });
  } catch (e) {
    Utils.showSnackBar(e.toString(), Colors.red);
    setState(() => _status = 'Error: $e');
  }
}

There is so much hiddenly going on with the requestDevices method. Is there any way to somehow debug this on the remote server ? Or can you explain what it does exactly ?
