Hi,
before all, plug out adapter...
Did you get any CD with Adapter? Try to first install drivers from cd, and then plug in adapter, if doesn't work, try this:
On CD is got to be folder WinXP (or something like it-if you have XP, if you have vista, folder name is Vista), in which are drivers for manual install. copy ONLY that folder on desktop. go to add new hardware, and manual browse drivers, and browse to folder on desktop and install it. I had this procedure must repeat for 6-7 times, and it works. My adapter is D-Links, but other version. My desktop computer normally installed it Automaticly, but notebook have problems, and I installed it like I written.
I hope you understand

Sorry for bad English...
