Cannot find ports

Bug Report

Current behavior

Arduino-cli cannot find connected boards by command "board list". But Arduino IDE easily finds boards and upload scetches.
Previously used the arduino-cli version 0.3.6-alpha.preview version and everything worked

When i run "arduino-cli board list -v" output is

arduino-cli board list -v

Hi @LepikhinEgor what boards do you have connected? Is the corresponding core installed?

[LepikhinEgor]

Yes, i try connect esp8266(nodemcu) and and esp8266 core was installled. Then I tried to connect Arduino mega and uno, but they also could not be found
Used the old version(0.3.6) again and everything works

Also have this problem. Arduino IDE find board without problem.
