I have read, that JACK versions 0.x are preferrable for ALSA multi devices.
Did you sync your cards? It's possible via wordclock or S/PDIF. The second card must be set to take it's clock from the respective input.

I have used two devices, one for input and output respectively. This article may help, even though it is written for the M-Audio Delta cards. Be sure to use the correct channel count. Some cards - due to their chips - have more channels than you can really use.
