No, that is what I told you to do.

A patch has been submitted to add that device to the USB_DEVICE table. It is 
included in the wireless-testing git tree, but it is not in the mainline code 
(yet). After that patch was applied, the device worked for that reported.

I noticed that you are getting an oops from iwlwifi, and an ehci-hcd error. Are 
you also exploring these problems?

If possible, could you use the wireless-testing repo? That will get you the 
latest code for all wireless drivers, and the USB code will match mainline.
