I figured out the problem. You must use the Presonus ASIO drivers, not the WDM drivers. The ASIO drivers will support multiple FireStudio's, and the WDM drivers won't. I got this info from Presonus, and it works. I looked through the FireStudio user manual, and found nothing in it about this.
So once you install the Presonus Universal Control application, it will install both the WDM and ASIO drivers. If you have other ASIO drivers installed, like ASIO4All, it may be a good idea to delete them. Then in Sonar, select the Presonus ASIO drivers, then select all 20 inputs for both devices (the 16 mic inputs and the 2 x 2 SPDIF inputs) and everything should work.
Apparently WDM only supports 8 channels. This may be also be a function of the fact that I was daisy-chaining the two FireStudio's off one Firewire card. I previously used two M-Audio Delta 1010's. Because each one occupies a separate PCI slot, it appears that you then get 8 WDM channels per slot. With daisy-chaining, you only get 8 WDM channels per slot. If you used two separate Firewire cards you may be able to run the WDM drivers.
