Firewire Card 2 interfaces ?

Hi all 
 
Sort of new to firewire interfaces for my main home studio workstation running a dell precision T3500 workstation this thing is super quiet Win 7 pro 64 bit 18gb of ram 64gb ssd two additional drives 1tb and a second 2tb running 2 nvidia fx 4500 cards.
 
I recently just added a dell 2 port fire card my current new interface is a maudio profire 2626.
I would like to get a maudio project mix and was wondering If I can have both connected to same card one in one port and one in the other ?  again new to firewire been mostly using pci or usb fasttrack pro
 
Running sonar 8.5 and ableton live 9 suite Cakewalk my main daw plan to upgrade to the platinum this year.
Just love this community and seeing the constant updates  why sonar is my home :)
 
any adive would be greatful
 

If you are using ASIO drivers as a general rule you can only use one interface at a time.  However in some circumstances and with some manufactures if you are using two I/F of the same model you can use two.
 
I note that both the devices you mention have separate drivers so I doubt this will work unless you run with one of the other driver models.

Thanks for the info  I plan to use one interface for sonar and one for ableton. I mostly do ambient electronic so sometimes I will just start getting ideas out in ableton then Import stems to Sonar, I use ableton like protools for recording and tracking when I play with different instruments. 
 

You only need to use one interface in this instance, I assume you won't be playing both at exactly the same time. You may want to experiment with rewire to keep DAWs in sync. You could route the output of one DAW into the input of another if necessary. So use ableton to sequence and Sonar to record and monitor, or bounce down the output or whatever. Also never tried it but I wonder if drag and drop will work between them.
