Putting this here so I don't have to go searching again....
Tried to get a couple of usb adapters installed on MX linux (buster).
Initially i started with older TP-link USB adapaters
TL-WN821N and TL-WN822N
However whilst the driver would install and the device was listed in lsusb output, I could never get it working...
In the end I swapped to a netgear adapter A6210.
Using the following articles as reference I was able to get this working.

But these are the commands I used to install this.
git clone -b port-to-4.15 https://github.com/kaduke/Netgear-A6210.git
cd Netgear-A6210
make
sudo make install
I got some warnings during the compile, but everything worked when I plugged the usb adapter in.
