If those devices aren't the same model, you can use the vid/pid
options of the snd-usb-audio driver to force them to have a specific
index.

For example, my three USB audio devices have to following vendor/
product IDs:

0582:0007 Roland SC-8820
0582:0018 Edirol UA-1A
041e:3020 SB Audigy 2 NX

I use the following options to put them at index 4, 3, and 7,
respectively:

options snd-usb-audio index=3,4,7 pid=0x0018,0x0007,0x3020
