This seems to be a bug in the rt2570 module. Since you can also use ndiswrapper to drive these cards (at least those of us on intel boxes), there is a simple workaround: disable the rt2570 module. You can compile it out, or just add these two lines to your /etc/modprobe.d/blacklist:
# use ndiswrapper instead for rt2x00 devices: rt2570 panics kernel blacklist rt2570 With rt2570 disabled, my device works as expected, appearing as the wlan0 interface (ndiswrapper), rather than rausb0 (rt2570). -- Ralink Wireless USB/PCMCIA/PCI hangs PC https://launchpad.net/bugs/34902 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
