Job? Yes, it would be nice if one could have the distribution's setup
routines figure out all of the different combinations of sound card and how
the user wants them all set up. But not even the competition does that. 
Note that on my system, I plug in my usb Maudio Transit sound card, and
there it is as dsp1 and card 1, while my snd-intel8x0 is, from boot, there
as sound card 0 ( or /dev/dsp). No work whatsoever on my part. Now it
sounds like you were trying someting trickier, which even Windows does not
allow you to.

A usb will almost always come later in the chain than a hardware soundcard,
on ALL operating systems, because the soundcard is there at bootup and the
usb card is plugged in and out.

Ie, your demands were unusual and LInux was able to meet them, admittedly
with some effort to figure out how. 
It is also certainly true that Alsa is in desperate need of documentation.
Why don't you volunteer?
