problema

Español

Tengo Samsung Galaxy A51 (SM A515F) que ejecuta la última máquina oficial de desarrollo Android 10 y MacOS 10.15.

ADB La autorización se da, pero a veces (~ una vez por 30 minutos) se desconecta y muestra el diálogo nuevamente.

Sucede solo con este dispositivo (tengo ~ 10 dispositivos diferentes). He intentado diferentes puertos y cables USB (incluido uno que se envió con dispositivo) sin suerte.

Veo el dispositivo en la salida de ioreg:

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

pero no en el adb devices Salida:

  $ adb devices    List of devices attached   

Se conecta nuevamente solo después de algunos cuadros de diálogos y re-conexión repetidamente aceptados.

¿Cómo solucionarlo?

upd. Ahora simplemente se desconecta y vuelve periódicamente, a veces con aviso, a veces sin ella.

registros en el tiempo de desconexión (se eliminaron las líneas no relacionadas):

Original en ingles

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):
