Maybe that was because I just unloaded the rt2500usb module and loaded it again with nohwcrypt=1 without rebooting the machine. Then I removed the HW encryption, recompiled and reloaded and it did not work either. It started to work only after reboot. Does the HW encryption really work with any rt2500usb hardware? How can I help to fix it? Or maybe it should be disabled by default. > > Luis Correia > rt2x00 project admin -- Ondrej Zary
