LibUsbDotNet obtains the scan code data of the scan code box through the usb port, but the read data is incomplete and incorrect. The following is the specific implementation code: Insert code snippet here public void Open(int vid, int pid) { UsbDeviceFinder usbFinder = new UsbDeviceFinder(vid, pid); usbDevice = UsbDevice. OpenUsbDevice(usbFinder); ErrorCode ec = ErrorCode. […]
