Oh, sounds like a nice setup.

I think it is specified as: <devicetype>:<device>,<subdevice>

So in your case the devicetype you wish to use is hw, the device is 0->2 and 
subdevice depends entirely if the card HAS subdevices and if you wish to use 
them, I think it probably best to leave it at 0.

so:
hw:0,0 (first card)
hw:1,0 (second card)
hw:2,0 (third card)

As I understand you brutefir supports natively to use several cards. If this 
is not the case then it IS possible to glue the cards together so they form 
one "card". This requires .asoundrc trickery that is beyond most peoples 
abilities though ;)
