Help Me Please with my FW port

Hello Everyone,

Here is my problem..

I have the tascam FW-1082 and I just bought the Adaptec FW 4300 card..
I installed it and Vista automatically installed the drivers and says
it's ready to go, however when I plug in my Audio device in there is
nothing, when I plug in my Video device(Canon ZR500) there is nothing..
However when I plug in my video device in the factory FW ports it pops
up, so I take it that the FW card I installed is not first priority..
How do I make it first priority? Or unless you guys have other
