[android] Moto G Pure: Connecting too briefly?

[Andersama]

I've now tried a Yubikey 5 NFC and Yubikey 5C with the same results, I have a suspicion I'd be dealing with the same problem with any model. In the app there's no recognition that a device has been connected. I don't get a prompt that a usb device has been connected like I would for file transfers etc. However if I'm in the USB Preferences menu both devices appear to be doing something for a brief moment as the menu is flashing between a disabled and enabled state very rapidly.

I've found seemingly unrelated articles about usb devices having problems that sounds vaguely similar. I can only assume there's some android setting which is not set properly. I'd be happy to log any debug info if anyone can walk me through how to do that. I found documentation saying to report issues about android here, which seems a bit strange because I think this is more to do with android than this app.

I can now confirm a similar model phone works, so I suspect its an android setting causing problems.

Hi! Sorry to hear that - could you let us know what Android version is your device running? Some phones have a feature called USB OTG which needs to be enabled otherwise the OS will ignore a connected device.

To help to understand what is broken, could you create a TRAFFIC log in the app and share it with me? The log might expose user data, so please hide all the received bytes.

Sorry, been distracted with holidays, sure I'll try to create a traffic log. How do I go about doing that?

Edit: I tried a soft reset which seemed to not work, however now (I haven't changed things since), it appears to be working.
In the about section it says Android Version 12 and the build number is S3RHS32.20-42-10-4-2-15-2-4. For more context I have a usb adapter I was using for the one key, and now I'm realizing that the adapter had a power led that was blinking which is solid now. Would the OTG setting prevent power from going to a connected device?

Thank you for the update. I’m afraid the USB adapter could be causing the connection issues, as I’ve had a similar experience. What type or brand of adapter are you using? Could the blinking be an indication that it’s continuously reconnecting?

[Andersama]

Well, I'd have agreed with you that it was the adapter if only one version of the key was a problem. I can only guess that USB OTG setting was in the wrong state and it took a soft reset for it to "fix itself". Although it wasn't immediate which is especially confusing.

Glad it got sorted out. Dealing with this kind of connectivity issues can be tough to troubleshoot, thanks for keeping us in the loop.
