I'm having an issue with my raspberry detecting the Alfa antenna I got.
I'm trying to configure and get up running the Alfa AWUS036NH on my Kali linux system (Image here. Kali Linux RaspberryPi 2 (v1.2), 3, 4 and 400 (64-Bit)), which is installed on the Raspberry pi 4 model B.
When plugging the Alfa USB cable in the booted pi (I tried all the USB 2 and USB 3 ports), the Alfa signal LED lights up and stays lit. So I am assuming the system is powered up correctly.
I have read that the antenna is supported out-of-the-box by kali, and that it should be detected without further action. Though it looks like it is not on my system, because the antenna is not detected by the system in any way. (I did not install any driver).
I have also connected the raspberry to my local WiFi before inserting the alfa into the raspberry, so I do have an internet connection via the pi's internal network card.
I'm running kali on a headless pi over ssh. The alfa antenna was connected to an USB3 port prior to booting the pi.

dmesg stdout: here
The alfa does not show up anywhere, and I can't seem to find a reasonable solution.
Edit 1: after installing Kali 2021 on a notebook and doing the same procedure, the result is the same. Alfa light on, no usb signal, network interface not detected.
Edit 2: downloaded drivers from official website but they do not provide any instruction for compilation, and running make as described in the provided readme does not work. Also tried unsuccessfully installing https://github.com/aircrack-ng/rtl8812au with an error described in issue #774
