i just bought exactly the same crap i even tried the phone number on the bit of paper that came with it, sounds like a kebab shop or something tried every port and still nothing tried it on my windows 7 and my mates xp still no joy if you eventually susss it please let me know cheers col 
You tried it on your friends XP? suprised it didn't work on that ...
Does the LED on your cable light up when you plug it in to your laptop? mine doesn't, but then Windows does detect a new hardware has been plugged in, so I suppose thats irrelevant.
The sellers got flawless feedback so im presuming we just have no clue on how to get it to work.
HENCE IM REQUESTING HELP!!!! ...
