UsbSerialConnected event on usbHost object?

I see here:
https://www.ghielectronics.com/docs/36/usb-host

The issue of serial communication is discussed, but i don’t see that option on my object, is it only valid from 4.3? (I’m using 4.2 and the only events are: keyboard, mouse and usb drive.

Thanks

@ andre.m - I opened the definition of the UsbHost on the code and I don’t see that.
The question is, is this issue resolved in 4.3? Should I upgrade? Or maybe i need to add something…

@ andre.m - Anyway, I installed 4.3 and I still don’t see it, what am I doing wrong?

        public event USBHost.USBDriveDisconnectedEventHandler USBDriveDisconnected;

and I am looking for the following events:

    private static void Controller_UsbSerialConnected(object sender, UsbSerial usbSerial)
    {
        Debug.Print("UsbSerial connected.");

        usbSerial.DataReceived += usbSerial_DataReceived;
    }

    private static void usbSerial_DataReceived(UsbSerial sender, UsbSerial.DataReceivedEventArgs e)

I can see the correct items fine. GHI.Usb.Host.Controller.UsbSerialConnected…

Did you change the project framework to 4.3? This is done through the projects property page…
