Hello,

I want to incorporate the reading of a barcode scanner into a plugin. The
barcode scanner is connected through a USB connection.

In a standalone program, I can acquire the reading by

public static void main(String[] args) throws Exception{
        InputStream in = System.in;
        int b;
        while (true)
        {
            b = in.read();
            if (b==-1) break;
            // do something...
            System.out.println((char)b);
        }
       
    }

But when I code it in imageJ plugin, it doesn't work. Basically, imageJ gets
completely stuck (Not responding).

Any ideas how to solve it?

Thanks in advance,

Emilio
