SerialPort.Net returned device can't be initialized
Describe the issue
I'm trying to retrieve a SerialPort device, it gets inside devices (IEnumerable<ConnectedDeviceDefinition>), as I can see WindowsSerialPortDeviceFactory is retrieving it from the Registry (because it has a label assigned), but when I try to read/write to it it says 'The device has not been initialized.'.
Is the device at fault? Because I see that it provides too little info down below (buffer sizes, etc.), but when I use it with other programs like Realterm to test it, it connects to the COM port and works.
Is there something else I can test? Thanks

Also I don't know if this might be a problem, but the device is supposed to be using a baud rate of 2400, I tried instantiating it manually with WindowsSerialPortDevice (by providing the port, baud rate, bytes, ...) but it's not helping, it still does not initialize.
I was trying with a RS232 adapter to USB, now I tried with a serial USB cable (on another port of the device) and it's initializing but I get an error during write/read, I guess that it's something inside the Windows ApiService
Just tested out with the default class SerialPort (System.IO.Ports) and it works, is there any reason why you are not using this package in your library?
Hi @Xriuk.Thanks for the detailed information. I had hoped to spend more time on serial ports but unfortunately, it was just never a priority because there is so much need for Hid stuff.
I notice here that you are talking to two possible devices: hid and serial. This is exactly what this framework was designed for so so it's a shame that it's not working.

I think this would require an extra nuget package. However, you can create your own factory to do this

Hi, just wanted to add that System.IO.Ports is in the .NET Core BCL since .NET Core 2.0 and is also in the regular .NET Framework. It's not a part of .NET Standard 2.0 but does support that standard.
One option could be to add a .NET Core target alongside netstandard2.0;net45, then reference the package on the .NET Standard target while avoiding the extra package reference on the other targets.
