Belkin wireless adapter install

Hi there, i cant get windows to recognize the adapter. First i downloaded
the software from belkin and installed it. I plugged the adapter, F5D7050
version 3.xx, into a usb 2.0 card i installed in the computer. When i
restarted the computer it said adding hardware and in device manager it
appeared under the USB host controller column. When i click the Belkin
desktop icon it says cant detect adapter, please plug it in. I even tried to
add the .inf file manually in the device manager and it didn't work, it said
doesnt contain info on your hardware. Is there another way to install this
driver? Thanks in advance.
