Got similar problem when a USB Type-C earphone is plugged, app crashed on start with following expection:

My app does not need USB support, I also commented out usb permissions in Manifest, why this happened?

Hi Gerhard, is your `targetSdkVersion` is 29 or higher? I found some reason here:

https://developer.android.com/reference/android/hardware/usb/UsbDevice#getSerialNumber()

Because I submitted my apk to Play Store and it asked me to update `targetSdkVersion` to 29, so I changed from 26 to 29. And according to the doc, this method, is the only one that throws Exception when app have no permission to USB device, and this only happens when `targetSdkVersion` is 29 or higher.

Since original getSerialNumber returns "" when no SerialNumber returns, I think it's not important so I use the following patch to ignore this Exception:

```

+
+            }
         }
         if (result == null) {
             result = "";
```

Need some devs to tell us how to handle it properly, it sounds like that SDL just want to see how many usb devices attached when it starts (but not interact so no permission needed here), and SDL gets some info of them, then Google suddenly say that you need to ask permission for one of the info...

Can use your earphone for listening and speaking? There are the audio subsystems, SDL2 uses.

Yes, it is SDK version 29. Well, I require a permission for using the gamepad. I don't get any exception when the gamepad is not connected. So it somehow makes sense to me. Can you still use a USB C Gamepad with your diff or do you have to reconnect while your app is running?

@Gerhard Sorry I cannot provide further info because this log is from my friend actually, I cannot reproduce it on my phone, but when I send my app to him, him got crash and send this log to me...

Hello, recently someone reported a crash in one of our projects that uses SDL. The crash happends when they tries to plug in physical keyboard or joystick. Since the logcat is same as the OP posted, I'd be worth to add the solution here. Add this intent-filter to AndroidManifest.xml:

<intent-filter>
  <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>
