The windows driver app one does not yet work with Mandrake any version.
If it hasn't found your card it does not have the driver so if you want wireless get a card that works with Mandrake or change your distro,
There are far more drivers installed on Suse and Mandrake doesn't seem to be getting very far with wireless drivers I guess it's low on their priorities.
Type iwconfig in a terminal to ensure it hasn't found your card/usb.
A tip if you want wireless to work with mandrake -without waiting for mandrake to come up with wireless drivers- get an access point connect it to your ethernet port and switch it via a browser to slave mode. Most access points have this facilty, check before buying though.
