If you want to go for convenience then you should just have a list of
VID/PID pairs to be used to generate maps and rules, which is what most
applications apparently do.

My program just parses the file provided by the package with the list
of supported devices and is barely about the "quick hack" level, I do
not think it's much interesting but here it is.
