I have micro:bit attached to my laptop on which running Xubuntu 18.04.4 LTS.
After I attached micro:bit an icon appeares on XFCE4 Desktop which can to use to mount this device to
/media/MyUserName/MICROBIT/
This way I can pair the device 'BBC micro:bit CMSIS-DAP' and my laptop by using https://python.microbit.org/v/2.0 in my Google Chrome browser.
But in mu-editor I can't do this, can't use neither REPL, nor FILE because I get this message box:
"Colud not find an attached device
Please make sure the device is plugged into this computer.
It must have a version of MicroPython (or CircuitPython) flashed onto it before the REPL will work.
Finally, press the device's reset button and wait a few seconds before trying again."

This line above is for the micro:bit attached.
$ ls /dev/ | grep tty
In the output of the command above there is not a /dev/ttyACM0 or other ACM* device out there.
Why is not there such a device /dev/ttyACM* out there?
I suspect mu-editor does not find the device because there is no such device /dev/ttyACM* out there.
How can I solve the problem for mu-editor?
I installed Xubuntu 20.04 and on this system mu-editor works in the Files mode and REPL mode with the attached micro:bit.
