I don't know of any shipping consumer device that uses that model anymore. In that process the CHID, CDID, and CKEY exchange is done by plugging the wireless device into the host PC once before it can be connected wirelessly. Devices currently on the market such as this: http://store.warpia.com/product_p/SWP120A.htm?gclid=COCZpvHo77wCFSFo7AodQg0AWA use either the ConnectToMe association method that was included in the WUSB 1.1 draft spec or some proprietary version of that. The devices I have been using are targetted for industrial environments and come pre-associated with each other. The CHID, CDID, and CKEY values are provided with the device and thus will work with the existing Linux driver. So the short answer is that I don't know of any consumer WUSB product that will work as is under Linux. Sorry.
