Most Helpful Customer Reviews

I recently purchased a new PC (with Windows 7 Pro) that did not have as many USB ports as I needed. I purchased this product and easily installed it. Windows recognized the new hardware and I thought everything was fine until I shut down. My system hung up and ultimately I got that wonderful 'blue screen of death'. No amount of manipulation fixed the issue. No other drivers solved the problem. As soon as I pulled out the card my PC worked perfectly. I don't have any idea why Windows 7 is so particular about adding a card with only a few external USB ports. Windows XP had no trouble with the exact same card. This is another case of let the buyer beware. Don't buy any hardware to put into your Windows 7 machine unless the manufacturer very clearly states the item is guaranteed to work with this operating system. I ended up finding an external USB hub, whose instructions specifically state that the item is certified for Windows 7.
Though undoubtedly deserving of the better reviews about this product, I have owned and attempted installation of two of these in my Hewlett-Packard h9 1100z 8-core computer. It has a Gigabyte 2AC8 1.2 motherboard and upon installation, it will not permit the system to even begin to load. Not even the informational screen on most computers denoting the description of video cards, etc. These installed-attempts were checked by others besides myself and found to be properly done, but sadly, this is the result. We even tried it with different power cords etc, to no avail. Power for these USB cards comes directly off the 600 watt power supply, so no problem as there is a USB 3.0 card on the same wiring loom which works properly. These were my results. Further checking on other boards has confirmed this to be the opinion of other writers.
Thanks amazon, for your excellent return process.
