Quick Start

Modify a Sample

The easiest way to get going to clone a repo that uses Usb.Net or Hid.Net and modify the code to suit your needs. Please clone one of the repos in Samples & Unit Tests.

Clean Project

If you want to start fresh, the easiest way would be to create a .NET Core project on Windows with Visual Studio and add the NuGet packages you require.

Example Code:

This is UWP code. The only difference for Windows is that you would call WindowsHidDeviceFactory.Register().

        private static async Task InitializeTrezor()
        {
            //Register the factory for creating Usb devices. This only needs to be done once.
            UWPUsbDeviceFactory.Register();

            //Register the factory for creating Usb devices. This only needs to be done once.
            UWPHidDeviceFactory.Register();

            //Note: other custom device types could be added here

            //Define the types of devices to search for. This particular device can be connected to via USB, or Hid
            var deviceDefinitions = new List<DeviceDefinition>
            {
                new DeviceDefinition{ DeviceType= DeviceType.Hid, VendorId= 0x534C, ProductId=0x0001, Label="Trezor One Firmware 1.6.x" },
                new DeviceDefinition{ DeviceType= DeviceType.Usb, VendorId= 0x1209, ProductId=0x53C1, ReadBufferSize=64, WriteBufferSize=64, Label="Trezor One Firmware 1.7.x" },
                new DeviceDefinition{ DeviceType= DeviceType.Usb, VendorId= 0x1209, ProductId=0x53C0, ReadBufferSize=64, WriteBufferSize=64, Label="Model T" }
            };

            //Get the first available device and connect to it
            var devices = await DeviceManager.Current.GetDevices(deviceDefinitions);
            var trezorDevice = devices.FirstOrDefault();
            await trezorDevice.InitializeAsync();

            //Create a buffer with 3 bytes (initialize)
            var buffer = new byte[64];
            buffer[0] = 0x3f;
            buffer[1] = 0x23;
            buffer[2] = 0x23;

            //Write the data to the device
            await trezorDevice.WriteAsync(buffer);

            //Read the response
            var readBuffer = await trezorDevice.ReadAsync();
        }
