Resolving ADB Connection Issues on MacOS

Resolving ADB Connection Issues on MacOS

30 November 2024 Stephan Petzl Leave a comment Tech-Help

Encountering issues with Android ADB debugging on MacOS can be frustrating, especially when you’re trying to connect devices like a Nexus 6 or other Android devices via USB. This guide offers a detailed approach to resolving a common error message: “Could not open interface: e00002c5”, which indicates that another application or driver might be using the device.

Understanding the Problem

The error code e00002c5 often signifies that your device is being accessed by another application or driver, preventing ADB from establishing a connection. This can occur due to various reasons, including open applications or processes on your system that hold onto the USB interface.

Steps to Resolve the Issue

To tackle this problem effectively, follow these steps:

1. Check for Open Applications

  • Ensure that no other application is currently using the device. For instance, if you have a tab open in Chrome at chrome://inspect/#devices, it might be causing the issue. Close any such tabs.
  • If you’re using any development environments like the Tizen IDE, ensure they are closed as they might interfere with the ADB connection.

2. Restart the ADB Server

  • Run the following commands in your terminal:
adb kill-server
adb start-server

3. Verify USB Connections

  • Try using different USB cables and ports to ensure the connection isn’t physically compromised.
  • Switch USB configurations on the device between Charging, MTP, and PTP, ensuring proper authorization for the Mac’s RSA fingerprint.

4. Check for Virtual Machine Conflicts

  • If you are running a virtual machine via software like VirtualBox, ensure that the device is not being accessed by the VM. Uncheck the device in the VM settings under USB.

5. Reauthorize the Device

  • If the device was recently connected, you might need to delete the authorization on the phone and reconnect to reauthorize the connection.
