Problem with Fritz!WLAN USB Stick N

[Leander Jedamus]

Hi!

I read that a Fritz!WLAN USB Stick N should work with Ubuntu 10.04. But 
I have problems on my two machines. The Hardware seems to be okay, 
because the Stick runs unter Vista with no problems.
I noticed that the LED's are not blinking the same way as under Vista. 
In /var/log/messages there is the following:

My one machine is a AMD Turion X2

What can I do now?

Thanks in advance
