I am a noob, butt wanted to say that I was able to get the AWUS036NHR working and injecting (on KDE and Gnome). I actually followed this instructions at the begining of this thread with two minor changes:

+First,for KDE, I changed the build and installation drivers wget

Code:
cd /usr/src/
wget http://www.orbit-lab.org/kernel/compat-wireless/2012/04/compat-wireless-2012-04-15.tar.bz2
tar jxpf compat-wireless-2012-04-15.tar.bz2
wget http://www.backtrack-linux.org/2.6.39.patches.tar
tar xpf 2.6.39.patches.tar
cd compat-wireless-2011-10-06
make
make install
+Second, I kept the udev persistent rules on my card.


As for Gnome I made the same changes except pointed them to the correct drivers. As for the patches I read that the 2.6.39.patches.tar were also for the current version of Gnome as of 20Apr.

+First,for KDE, I changed the build and installation drivers wget

Code:
cd /usr/src/
wget http://www.orbit-lab.org/kernel/compat-wireless-3.0-stable/v3.2/compat-wireless-3.2.5-1.tar.bz2
tar jxpf compat-wireless-3.2.5-1.tar.bz2
wget http://www.backtrack-linux.org/2.6.39.patches.tar
tar xpf 2.6.39.patches.tar
cd compat-wireless-3.2.5-1
make
make install
(When I did the make and make install command, I recieved some errors. So I ignored them and didn't write them down because I am a noob.)

+Second, I kept the udev persistent rules on my card.

As a result, I used aircrack-ng in KDE and Gerix in Gnome to successfully crack my WEP.
