The only changes are in the rtlwifi drivers. I don't have a USB 3 device, thus I have no idea what might work there. I wrote something incorrect earlier. The new code is not in mainline 3.3, but it is in the wireless-testing git tree. If you want to try this, and don't want to get the whole tree, the new code is in the bleeding-edge compat-wireless package. Otherwise, I could send you the patches. Larry Larry
