Comment 7 for bug 553782

When the Ndiswrapper with the Ralink proprietary Windows Driver is used after removing the active module rt2500usb the device works (ofcourse using NDIS).

But when removing the ndiswrapper and its module, and modprobing the rt2500usb again "rfkill" will show soft and hard unblocked. Continuing that when doing:
sudo ifconfig wlan0 up
sudo service network-manager stop/start

The device connects and functions fine with the rt2500usb driver, also shown in the connection info box of network-manager applet. It really doesn't use the ndis because there are no ndis modules loaded. So the kernel driver works fine, but there really is problem getting the right "hard blocked" state.
