Summary: Better than a HUB
Review: Some devices just work better when directly connected instead of with a hub. I bought this to give my system extra ports and it works great, no problem to install.

Summary: No Problems. Easy Installation
Review: This card is working fine for me so far. I read a review here that said this card slowed down their system by 50%. I did not experience any slow down. To be sure of this, I ran a benchmarking program before and after installing the card, and the results were the same within the measurement error (determined by running the benchmark a couple of times before installing the card). I installed the card on a WinXP (SP1) machine with an AMD Duron 1.3 GHz CPU and a KM266-8235 motherboard. Perhaps the other reviewer had problems due to an older system? (just a guess).
Installation of the card was easy. Just plug it in and WinXP identified it immediately.

Summary: Some things are not what they seem to be!
Review: This promising 6 port USB card caused my machine to "hang" because of the substantial overhead required by the USB 2.0 operations. I have a 3 year old 800MHZ machine with 256MB of ram. Adaptec says it requires "266MHZ or faster". I spent one hour on the phone with tech support ... trying a myriad of 'fixes' none of which worked. The tech ... said ". . . 800MHZ is marginal speed (!), a 3 year old machine predates the USB 2.0 spec and frequently the 2.0 cards will not work in a machine like this!!!" ...

Summary: No problems. Very fast. Easy install
Review: To be honest, I've no real comparison to make. I bought this primarily in conjunction with a new scanner (Canoscan D125OUF). Before the card arrived, it was hooked up to USB 1 and I was still impressed with the speed! The last scanner I used was a few years old, so this was a vast difference. USB 2.0 is supposed to be 40 times faster and maybe it is. The scanner is just as fast using USB 2 although it's hard to tell how much faster it is.Having said that, the card was simple to install, driver/hardware was a breeze (using Windows ME) and no problems have arisen.
