The same thing happens in windows

Extension version: 0.2.27
VS Code version: Code 1.40.0
OS version: Windows 10 pro 1903 (build 19018.1)

I have the same thing on a Linux Mint (Debian/Ubuntu) system. The ArduinoIDE packages work, but VS Code doesn't let me select a serial port. This seems to be the same thing as issues #596, #664 , #816, and/or #851. The release of 0.2.27 fixed this problem for some people, but not everyone, it seems.

If I edit the .vscode/arduino.json file directly and add the line for the serial port path in my case to:
"port": "/dev/ttyUSB0",

The VS Code interface picks up the configuration change and can program the Arduino Uno. When I try to bring up the serial console I get:

"Failed to open serial port COM6 due to error: + TypeError: Cannot read property 'close' of null"

vscode-arduino version: 0.2.27
vscode version: 1.40.0
Electron: 6.1.2
Chrome: 76.0.3809.146
Node.js: 12.4.0
V8: 7.6.303.31-electron.0
OS: Linux x64 4.15.0-65-generic

I have read/write perms on the serial port and can run other tools without priv escalation to read/write just fine.

To sum up:

• The "Select Serial Port" button and menu option don't bring up a menu.
• Setting the serial port in the json file manually allows programming, but not use of the serial console.

I am having this problem as well on Windows Version 10.0.18362 Build 18362.
vscode-arduino version: 0.2.27
vscode version: 1.40.0

I can interact with the serial device via PuTTY, and I can also set the COM port in the arduino.json, but the button at the bottom right and the Command Palette command both do nothing as far as the UI is concerned.

Same issue here - Nothing shows up after clicking the <Select Serial Port> button.

I have the same issue, clicking on a COM port name in status bar does nothing.

My set up is as follows:

Extension version: 0.2.27
VS Code version: Code 1.40.0 (86405ea23e3937316009fc27c9361deee66ffbf5, 2019-11-06T17:02:13.381Z)
OS version: Windows_NT x64 10.0.18362
Arduino IDE: 1.8.10

[jrlanglois]

Quick update: testing out vscode 1.39.2 (instead of the latest, 1.40.0) and the COM port selection works just fine.

[acrandal]

I can confirm @jrlanglois finding that vscode 1.39.2 has a working serial port selection.

Duplicated with #918 #927 due to VSCode engine bumped to 1.40 with Electron 6.0 update.
