: Hi Warner,

: why not do it the other way round? Keep them out of GENERIC, but have
: loader(8) load some of the most used modules (snd_driver!) per default.

Because the meta-data necessary to know which module to load doesn't
presently exist in a standardized enough form to make this a viable
option. Each driver does its own thing to match the cards, and
there's no easy way to know that any given usb device needs module
foo.
