The modules load when I plug the stick in but I then get a complete kernel lock up with two flashing leds. Nothing is recorded to system logs. The last logged messages are that usbcore has registered new interface driver rt73usb, and that the rate control algorithm has been selected on phy0. This happens whether the simple or pid mac80211 rate control algorithms have been chosen. This is a shame because 2.0.14 was working really well for me until the mac80211 changes 2 or 3 weeks ago broke it. (Shortly followed by the release of 2.1.*).
