I used the Linksys WUSB600N previously with a driver and kext I downloaded from http://www.ralinktech.com/support.php?s=3 and look in the contents of the Kext. I would suggest you download the 3572 version. I merely changed the name and device id to 47 and maker to 5041 in IOKitPersonalities in the info.plist file. I presume you know how to do this.
