Doesn't work in WIN 8 or 8.1 without getting a special driver which Norton reports as a Threat every scan. I don't know if it really is but I'll be looking for a WIN 8 / 8.1 certified one to replace it. It works OK on my old XP machine I use for a Logic Analyzer and don't connect to the WEB so it's not a complete waste of money.
