have you tried this?
Unplug your Saffire LE
Open Computer Management, go to Device Manager.
Expand IEEE 1394 Bus host controllers
At this point you probably see Texas Instruments OHCI compliant controller or something
Right click on it and click Update Driver Software
Then click Browse my computer for driver software
Then click let me pick from a list
You should get at least three options.
Select 1394 OHCI Compliant Host Controller (Legacy)
Let that install.
Once it's done, reinstall the Saffire LE 1.3 drivers (this step possibly optional)
Now plug the device back in
if it's not happening in the room, it ain't gonna happen on tape.-HG
