This is hard to find. Should work with all W2k and XP O/S's. The card has a Genius sticker and a marking Vanta AL on it + a serial No. GJE23559. But I couldn't find a Genius Driver. The Driver is from the manufacturer Gainward, Taiwan. I found this by searching variations of the FCC ID, which is ICUVGA-GW909A. This is working fine on my system now.
