adb blinks with 'emulator-5554 [DISCONNECTED]'

Question

I've a device connected via USB (Samsung SM-T385 - Type C Port) and I don't have any emulator created in my system.

OS : Ubuntu 16.04

ADB Version : Android Debug Bridge version 1.0.40 ; Version 28.0.2-5303910

Problem

Even though I haven't added any emulator, adb blinks with emulator-5554 [DISCONNECTED] like above. Sometimes even the real device is not getting detected, and shows just the blink text. This issue also occurred to one of my colleagues. He uses a Windows 10.

What worked?

Restarting the system solved this issue for an hour or less,then the issue rises again.

What didn't work?

adb kill-server
Kill adb from process list
Restarting Android Studio

Question

How do I fix this issue, without restarting the system ?

Assuming ANDROID_HOME is the path of the root sdk folder, post the result of this command: `$ANDROID_HOME/tools/bin/avdmanager list avd` — Sepehr Behroozi, Mar 27 '19 at 11:30

Please add some explanation to your answer such that others can learn from it - what makes you think that changing the port number solves the original problem? – Nico Haase Jul 02 '19 at 09:49
