How to communicate with a device over USB from C# desktop application
1)I want to communicate with device send data to device/read data from device over USB port using C# desktop application. I have been using SerialPort from C# application and it is pretty simple. I do not know how different it would be for USB port.
2)Now I want to switch my code from communicating to a device via serial port to USB port. Do I need any additional dll/driver/library etc in order to do that.
