C # Implementation of USB communication based on Libusbdotnet (I.)

Online C#USB communication information is relatively small, basically is based on Libusbdotnet and Cyusb, about the printer equipment and there is a opos.

This post is based on libusbdotnet.

1. Download and install the Libusbdotnet installation file.

2. Run the filter Wizard, Install a device filter. Install a USB device that requires communication.

　　

3. Build a simple console project to test for printing information that requires communication equipment.

Printusbinfo

 public static void Printusbinfo () {Usbdevice usbdevice = null;            Usbregdevicelist alldevices = usbdevice.alldevices;            Console.WriteLine ("Found {0} devices", Alldevices.count); foreach (Usbregistry usbregistry in alldevices) {Console.WriteLine ("Got device: {0}\r\n", Usbre Gistry.

Call

public static void Main (string[] args)        {            printusbinfo ();            Wait for user input            : Console.readkey ();        }
