Android device not showing with adb

I searched for this for a long time, I tried all the tricks I could find ...

I've been debugging the same device for months now, deploying the app to other precise devices without error. But since last week, I can no longer connect to it. When I connect the device via USB, I hear the computer beep for the connected device, and I can see in Chrome that it is recognized

However adb won't detect it.

Unfortunately I don't have root access on the devices, so I'm not sure how to connect over TCP / IP.

What could be the problem?

Note: I am working with Ubuntu.

Note 2: Devices are running Android 4.4.2 as reported by the device, even though specifications from different vendors say otherwise.

Update

I have checked my UDEV rules so

$ lsusb
...
Bus 003 Device 123: ID 1f3a:1002 Onda (unverified) 
...

is the only device added when the tablet is connected via USB. And in my /etc/udev/rules.d/99-android.rules

file (which I already installed over a year ago) I have the correct line

SUBSYSTEM=="usb", ATTRS{idVendor}=="1f3a", MODE="0666"

Since you have Chrome Remote debugging running, just make sure Chrome debugging is not working when you do something with adb on the command line.



I believe Chrome has its own version of adb server which will conflict with the one used by Android Studio.

You need to enable developer mode in Mobile first and then connect the device to your Linux machine. It doesn't require drivers, happy debugging.

Managed to execute session manager after:

sudo ln -s /snap/bin/anbox /usr/bin/anbox
Now the device

adb:

$ adb devices
