Hi,
I have a usb symbol barcode scanner that I want to trigger a 5v relay when data (barcode reads) pass through.
I want to be able to intercept the information without interfering with the normal connection and operation of the scanner and without ongoing background software on the intended host computer (i'm going to be installing this in a site I cannot monitor).
Any idea how I'd go about doing it?
