Schould work with entries in /etc/modutils/sound. The (main)modules for
devices have the parameter "index". So you would give one of them 0, 1 
and ... See modinfo <modulename> for that.

Modules get loaded at bootup from tools ala udev, hotplug, discover,
/etc/modules or, when plugged in later, by udev or hotplug. 

The above file "schould" do it, if not, try to put these parameters into
/etc/modules or edit the configuration file of the utility that loads
the modules on your machine. BTW: simply plugging in the USB device
after bootup will likely also do it.
