 Is there a way that I can reserve device 0 for the USB
device? It needs to
be reserved because the motherboard hardware is detected before the USB  bus
...
 is scanned - if the monitor is even turned on when the
system is booted. 
In theory one can cause ALSA to allocate snd devices to a particular alsa 
sound device number, I have though NEVER though in a good number of years 
been able to get this to work with any kind of relaibilty. 

...
 Is there a way I can make the system just ignore the
motherboard device
and have only 1 ALSA card?  There's only one thing that can ever be useful
so it seems best to make it the only recognised card in the system.  
There are two ways one can compile a kernel with only the sound device 
driver required present. The second method is simpler than anything else 
and does work. Do an lsmod and identify the main module that is loaded for 
the offending device then blacklist this module in .... 

/etc/modprobe.d/alsa-base-blacklist.conf (in debian anyway) 

This prevents the kernel loading the module.
