So i tried to use the wifi USB AVM Fritz Stick N v2 , USB ID 57c:8501 with Saucy and Trusty.
Unfortunately it fails to initialise properly.

According to the label on it , this device is powered by a Ralink RT5572N chipset.

The rt2x00 driver seems to recognize this device:

[ 0.000000] Linux version 3.13.0-19-generic (buildd@akateko) (gcc version 4.8.2 (Ubuntu 4.8.2-17ubuntu1) ) #40-Ubuntu SMP Mon Mar 24 02:36:06 UTC 2014 (Ubuntu 3.13.0-19.40-generic 3.13.6)

As we can see it fails to properly initialize the device.

I am running the most recent Kubuntu 14.04 64bit release that came out this week.

What i exspect to happen is that the device works and i would be able to connect to my wifi network, what happens instead is that only the ethernet card is visible and usable.
