Oh Kevin, where to begin!
First of all, don't take a manufacturer's word for anything. Really, the internal headers of motherboards are nine-pin, not 10. Really, the tenth pin is blanked out as a key, so that one-piece connectors can't be installed the wrong way. It's been 9-pin on most boards since before AC97 standardized it. BTW, the 97 means 1997.
Now, it blocks off TWO USB ports but uses only one? Well, I understand that news and reviews are done differently, but you could have at least tossed a hint in there. I mean, 30MB/s is pretty standard for a thumb drive, but this thing should be doing 60MB/s if it covers two ports, eh?
