This alone doesn't work when multiple devices are handled by the same driver.

The snd-usb-audio has a "pid" parameter to specify that a device with a
certain product ID should go to a specifc index.  For example,

        options snd-usb-audio index=1,2 pid=0x1234,0x5678

would force the device with product ID 1234 to come first.
Vendor and product IDs can be listed with lsusb.
