I have 3 belkin wireless adapters all in use. An older 'b' F5D6050
which installs and works fine; and two 'g' F5d7050, this comes in
several versions, 1000,2000,3000, all use the rt2500usb driver and you
need 'ndiswrapper' to install the windows drivers.
However version 4000 has Zd1211 driver which is automatically
installed and works 'out of the box', that's the easiest to install.
