Buffalo WLI-U2-KG54-AI Wlan usb card support!

Hi,

I have WLAN USB card mentioned in subject. I can't get it to work in Vista
Home Premium even after installing Ralink's Windows Vista drivers. After
installation of those drivers, it is listed when manually browsing available
drivers. Problem is that after plugging it in I can only see mass storage
device, in which drivers for previous Windows versions are, not the actual
WLAN side. Any help is much apreciated.

Regards,
Anssi

P.S. I also have A-link WL54USB WLAn card, but it won't work either...
