Query: Does not work with AUA-1420 USB 2.0 Card!

If you are purchasing this for an Adaptec CardBus card that you purchased because you need the extra power, look elsewhere. Even though Adaptec recommends this particular power cord for the AUA-1420 USB Card (and probably other ones, too), the plug on this cord is too big (5.5 mm outside vs. the 3.5 mm outside needed for the card). I end up building an adapter with parts from Radio Shack. Shame on you, Adaptec!
