Query: Did not work - had to return

I purchased this item because I am pretty much using all my USB ports, and I liked the idea of having high-speed ports for my high-speed USB devices. When I plugged it in, not only did it not carry my keyboard or my printer (it was like they weren't plugged in at all), but it also killed my other USB ports -- none of them worked after I plugged it in -- even after I unplugged it. I have NO IDEA what happened but after I did a system restore to the previous day, and then did a reversal of the system restore, then I had my USB ports back. I couldn't print out my return label fast enough. I am fairly saavy when it comes to technology, and I can say I may never buy a Belkin Hub again. Bad experience for this first time Belkin buyer and full-time web developer.
