Very true. haha.. The reason the model number of the PC is important to find is that you can look up that PC's entire package of drivers and make surey ou get the exact drivers that were shipped with that PC in the first place.
I have not searched for just a device on HP's site very often.. but every time I do I usually hit a dead end without the model number of the original PC.
Hope you can find it.. if you can get me thet model number of the PC I will poke around for you
