Lower bus speeds in IEEE 1394 driver

Hi all,

I am using a point grey research camera "Grasshopper" which I connect to the computer using IEEE 1394b bus. While using Labview Vision Acquisition I am not being able to go to frame rates higher than even 7.5 fps in Mono8 1024X768 resolution. This I think is significantly less than the max bus speed that I can achieve.

My computer has got Windows SP3, and the 1394 driver in it slows down the bus as I came to know from the web.

So working as per the suggestions of the PGR support I downgraded the driver to the SP1 version. Even then I am not able to go to higher speeds in Labview.

 

Please suggest.
