Write to HID with Chip Selection with .NET Console App

Hi I am writing a simple console app that needs to write bytes to MCP2210 USB to SPI Master
I found this library over here, seems to do good job with connecting the device and reading the metadata.

I am writing message to the board as below

 public static byte Talk()

        {

            var device = DeviceList.Local.GetHidDevices(1240, 222).FirstOrDefault();

            if (device == null)

            {

                Console.WriteLine($"Could not find a device with Vendor Id:1240, Product Id:222 ");

                return null;

            }

var reportDescriptor = device.GetReportDescriptor();

            foreach (var deviceItem in reportDescriptor.DeviceItems)

            {

Console.WriteLine("Opening device for 20 seconds...");

                if (!device.TryOpen(out var hidStream))

                {

                        Console.WriteLine("Failed to open device.");

                        continue;

                }



                    Console.WriteLine("Opened device.");

                    hidStream.ReadTimeout = Timeout.Infinite;

                    hidStream.Write(new byte[3] {60, 00, 00});

           }

Not sure If I am writing it correctly.
While writing I need to do a chip selection as displayed in this other terminal

Any help is greatly appreciated

I do not see a closing of your stream. This may cause your data to not even being sent (at least not in time).

Consider using blocks with streams.
But with out parameters not possible.
