Output of NovaLCT Mars and MiniComPort

I tried to run NovaLCT Mars in wine (added it to appdb).
http://novastar-led.com/down/software/Sync/NovaLCT-MarsV4.4.0Setup.zip

It didn't find any serial ports.

I was using dotnet20 and dotnet40 from winetricks.

Then I tried this:
https://code.msdn.microsoft.com/windowsapps/SerialPort-Sample-in-VBNET-fb040...

When starting the serial port sample (MiniComPort.exe) it throws
IndexOutOfRangeException.

By looking at the source code it seems that
System.IO.Ports.SerialPort.GetPortNames returns an empty list.

If I ignore the exception, the rest of the MiniComPort program works. It can
send and receive some bytes.

Inotifywait revealed that NovaLCT Mars doesn't open the ttyUSB device like the
MiniComPort.exe does.

I also tried with wine-mono-4.5.6 but neither of those programs starts that
way.
