[PlanetCCRMA] midiman usb audio4

[abi]

I did everything about hotplug blacklist and I edit my modules.conf
like this:

alias usb-controller usb-ohci

#modem
alias char-major-212 slmodem
alias slmodem slusb

# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.4 ---
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-ali5451
alias sound-slot-0 snd-ali5451
# --- END: Generated by ALSACONF, do not edit. ---
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
alias snd-card-1 snd-usb-audio
alias sound-slot-1 snd-usb-audio

options snd major=116 cards_limit=3 device_mode=066 device_gid=0 
device_uid=0
options snd-ali5451 index=0
options snd-usb-audio index=1

add options -k snd-card-0
add options -k snd-card-1
#-------------------------------------------------------------------------------

I configured also the stupid ali card but my laptop doesn't see my usb card,
the module snd-usb-audio is loaded and (strange) if I want to restart 
alsa driver
the computer say that snd-usb-audio is busy and doesn't stop it.
I'm on RH9ccrma kernel.
Is there anybody who could help me please

ciao
