Well, it does not work. This is what my asound.conf looks like after
boot with usb device plugged in:
$ cat /etc/asound.conf 
defaults.ctl.card 0
defaults.pcm.card 1
defaults.pcm.card 0
defaults.pcm.card 0
defaults.pcm.card 1
defaults.pcm.card 1
defaults.pcm.card 1

This is what I would like to have:
defaults.ctl.card 0
defaults.pcm.card 0

These are the udev rules, any idea what's wrong with them?
$ cat /etc/udev/rules.d/00-local.rules 
KERNEL=="pcmC[D0-9cp]*", ACTION=="add", PROGRAM="/bin/sh -c 'K=%k; K=$${K#pcmC}; K=$${K%%D*}; echo defaults.ctl.card $$K > /etc/asound.conf; echo defaults.pcm.card $$K >>/etc/asound.conf'"
KERNEL=="pcmC[D0-9cp]*", ACTION=="remove", PROGRAM="/bin/sh -c 'echo defaults.ctl.card 1 > /etc/asound.conf; echo defaults.pcm.card 1 >>/etc/asound.conf'"
