This was working great for a little over a year. Got less than 10 coasters over that time of burning hundreds of discs, and it did freeze on me while burning a few times. Now my computer running Windows XP Home SP2 just doesn't recognize it. It shows it as an unknown usb device in "Device Manager", and it doesn't even show up in "My Computer". Tried uninstalling and then reinstalling the installation program several times. It doesn't work. Windows says the driver is not installed(Code 28), and it also says the device is not configured correctly(Code 1). I thought the driver was suppose to be in the installation disc. I followed the instructions in the "Found New Hardware Wizard", but I can't get it to work. Does anybody know what to do? Can you post a link to get the driver? I tried the HP website, and they offered a driver/installation disc for sale and a firmware upgrade (ch16). I already have the upgrade and I don't need the installation disc because I already have it. Any help would be appreciated.
