Kali+Raspberry PI+Alfa AWUS036NHR

Hello everybody,
I have a little issue with USB Alfa AWUS036NHR WiFi running on Raspberry PI running Kali. Not a power issue.
Kali is able to detect Alfa, when it comes up wlan0 interface is up and running.
When I bring it down change the mac with macchanger and than trying to enable it with a airmon-ng start wlan0 it doesn't come up and i can see mon0.

Could you please advise what the **** is going on.

Code:
