Manually installing drivers on Linux Mint

I am currently trying to install a driver through terminal. It is for the USB UART XR21B1411 serial port adapter. I installed it in the past, but cannot remember how I did it. Here is a link to the driver: https://www.maxlinear.com/content/document.ashx?id=21651 As you can see, there is a Makefile, two .h files and two .c files. How might I install this driver? Any help would be greatly appreciated!
