yes it should light up when the driver loads properly and finds the card... so you're out of luck
maybe you could try the socket wlan (as i said there's a lot of them now on ebay). i can send you the socket driver.
edit: hmmm, sorry, this is the new version, not the black, earlier card... i dont know if the new drivers are compatible. you could try and ask at socketcom.com.
or install the drivers from their downloads page. if they're GUI less (and rely on zeroconfig), you have a good chance!
