AFAIK, `libusb` could not access common HID devices. You could try the differences - https://github.com/woodemi/web_usb.dart - https://github.com/woodemi/web_hid.dart Related: https://github.com/woodemi/quick.flutter/issues/57#issuecomment-1196041325

Could try https://github.com/woodemi/libusb.dart? ``` $ git clone https://github.com/woodemi/libusb.dart $ cd libusb.dart $ flutter pub get $ flutter pub run example/listDeviceProducts.dart ``` Then you could debug the `listDeviceProducts.dart` within VSCode

If you mean error of VSCode's code inspection, you should add JSON config into `.vscode\settings.json` ```json { "dart.flutterSdkPath": "C:\\Users\\sunbr\\w\\google\\flutter-3.0.x" } ```

Oh, I see. Since Dart 2.17 `ABI-specific integer types` are moved from `package:ffi` to `dart:ffi` We shoud use `import 'package:dart/ffi' as pkg_ffi` for Flutter 3.0+

Clean cache in `.dart_tool` may help according to https://github.com/woodemi/quick_blue/issues/102#issuecomment-1119171251

Thanks for your report. Does it happen on the old implementation or the new one? - old implementation in https://github.com/woodemi/quick_blue ```cpp SetNotifiableAsync(*it->second, service, characteristic, bleInputProperty); result->Success(nullptr); ``` - new implementation...
