Unable to select serial port

[zeier]

Issue Type: Bug

I have set up the development environment as described here: https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-arduino-iot-devkit-az3166-get-started#prepare-the-development-environment

With Tera Term, I'm able to communicate with the IoT DevKit over the corresponding serial port (COM5).

However, in VS Code, I cannot select a serial port (nothing happens when I click on "Select Serial Port").

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

As a workaround:

1. open the folder where your .ino file resides
2. open the .vscode folder
3. edit arduino.json
4. change the port
   e.g.

{
  "port":"COM4"
}

This is still an issue (v1.49.1)
