  You will not break your computer with what you have done. It appears that we still must blacklist rt2800usb in /etc/modprobe.d/blacklist.conf to get the device to work in kernel 2.6.32-21-generic. After that the device will work fine as long as the access point is unsecured. Trying to use WPA2 security however still fails to connect. I suspect something in wpa_supplicant or the linkage thereto needs to be fixed.
