problème

français

J'ai Samsung Galaxy A51 (SM A515F) exécutant la dernière machine de développement officiel Android 10 et MacOS 10.15.

L'autorisation de la BAD est donnée, mais parfois (~ une fois par 30 minutes), il se déconnecte et montre à nouveau la boîte de dialogue.

Cela ne se produit qu'avec cet appareil (j'ai ~ 10 périphériques différents). J'ai essayé différents ports et câbles USB (y compris celui qui a été expédié avec un appareil) sans chance.

Je vois l'appareil dans la sortie iOREG:

SAMSUNG_Android@00400000 <class AppleUSBDevice, id 0x100fbd4da, registered, matched, active, busy 0 (2 ms), retain 18>

mais pas dans le 9988777661 sortie:

$ adb devices List of devices attached

Il se connecte à nouveau qu'après peu de dialogues et de relacements acceptés à plusieurs reprises.

Comment le réparer?

upd. Maintenant, cela ne fait que déconnecter périodiquement et reconnecte, parfois avec une invite, parfois sans elle.

enregistre au moment de la déconnexion (lignes non liées):

I have Samsung Galaxy A51 (SM A515F) running latest official Android 10 and macOS 10.15 development machine.

ADB authorization is given, but sometimes (~ once per 30 minutes) it disconnects and shows the dialog again.

It happens only with this device (I have ~10 different devices). I've tried different USB ports and cables (including one that was shipped with device) with no luck.

I see the device in the ioreg output:

SAMSUNG_Android@00400000  <class AppleUSBDevice, id 0x100fbd4da, registered, matched, active, busy 0 (2 ms), retain 18> 

But not in the adb devices output:

$ adb devices    List of devices attached 

It connects again only after few repeatedly accepted dialogs and re-connection.

How to fix it?

UPD. Now it just periodically disconnects and reconnects, sometimes with prompt, sometimes without it.

Logs at the disconnection time (removed unrelated lines):
