Installing TP-LINK T4U (USB WLAN ADAPTER) on Kali Linux 2.0 VM impossible


Dear community,

I would like to introduce you to my problem.
About two days ago, I bought the TP-LINK T4U USB Wifi Adapter.
After that I wanted to install the necessary drivers on Kali Linux VM.
After I unplugged the device from the host and connected it to the VM, I installed the drivers.
But now there's a massive problem...
The system recognized the adapter and I can use it for WiFi connection establishing, so I know the installation of the driver was successful.
BUT STOP!
When I run
Code:
airmon-ng
I get a screen reporting:

Code:
PHY    INTERFACE   DRIVER      CHIPSET

phy0   wlan0        ?????
Why is there no driver installed?
I cannot run
Code:
airmon-ng start wlan0
because I get an error reporting:

Edit: I had already typed airmon-ng check kill and the processes were killed.
Code:
PHY	Interface	Driver		Chipset

phy0	wlan0		??????		 
cat: /sys/class/ieee80211/phy0/device/net/wlan0mon/type: No such file or directory

Newly created monitor mode interface wlan0mon is *NOT* in monitor mode.
Removing non-monitor wlan0mon interface...

WARNING: unable to start monitor mode, please run "airmon-ng check kill"
I think that I can't run airmon-ng because the driver is not compatible with airmon-ng. Does anyone now if it is?

I am new to Kali Linux and I haven't found anything about the compatibility of the adapter...

I followed the instructions from this webpages to install drivers:

Code:
http://wiki.beyondlogic.org/index.phptitle=TPLINK_Archer_T4U_RTL8812au_Linux_Drivers
Everything went according to the website but after I'd issued
Code:
sudo make install
I did not receive any information about the adapter!
Instead of
Code:

I saw this:
Code:

/sbin/depmod -a 4.3.0-kali1-amd64
Nope. Doesn't look good. And I think that this results in aircrack.

This is always displayed. No matter if the adapter is plugged in or not. I definitley know that it is the correct model and the correct driver. Why doesn't the system find the T4U?

I need help please...

did you READ the Kali documentation ?
http://docs.kali.org/installation/tr...-driver-issues

in particular their highlight in RED

NOTE: 90% of wireless issues reported to us are due to people not reading the aircrack-ng documentation. You need to run airmon-ng check kill before putting your card in monitor mode.

Same error.

So that is not the reason. Again, I typed:
Code:
root@NoPeWRonG:~# airmon-ng

PHY	Interface	Driver		Chipset

phy0	wlan0		??????		 

root@NoPeWRonG:~# airmon-ng check kill

Killing these processes:

   PID Name
   703 dhclient
   740 wpa_supplicant

root@NoPeWRonG:~# airmon-ng start wlan0


PHY	Interface	Driver		Chipset

phy0	wlan0		??????		 
cat: /sys/class/ieee80211/phy0/device/net/wlan0mon/type: No such file or directory

Newly created monitor mode interface wlan0mon is *NOT* in monitor mode.
Removing non-monitor wlan0mon interface...

WARNING: unable to start monitor mode, please run "airmon-ng check kill"

Fixed it by returning the old adapter and buying a new one.

Thanks for the support.
