I have a Pacific Digital CD burner. I added a 2.0 USB card for it which works since I plugged in another USB device and that worked fine. My hard drive does not recognize the burner. I get an Unknown Device in my Device Manager. When I use the software I get a message that it can't locate any CB burners. Any help would be appreciated since Pacific Digitals web site is pretty useless and their tech support is me leaving a message and they will "get back to me".
