Creating builds with other drivers

Hi

How do I modify/build the kernel driver source code on the RPI Volumio 2 so that I can add video drivers?

Thanks

The Vu7/Vu7+/Vu5 use a customized USB-raw driver.
So I need to port this device driver to the Volumio build
github.com/hardkernel/linux/blo … v-usb-mt.c

Just not sure how to do this.
