As a follow up to the email below regarding my new Texas Instruments 1394 driver (v.6.1.7600.20756) find:
My Flex 5000 has been humming along non-stop since Wednesday. That wouldve been impossible using the Microsoft 1394 drivers. The interesting thing is that I now see infrequent 4000µS DPC Latency spikes that I didnt have before. They dont affect the audio, however. If a driver is going to misbehave then I want it to be the 1394 one taking priority, which seems to be the case. My average DPC latency dropped from a solid 250 µS to the 80 to low 100 range. All good software comes from Texas.

Ive been using the 1394 OHCI Compliant Host Controller (Legacy) under Windows 7 x64 since it happens less often with it. Tonight I got the notion to right click on it in the Device Manager and picked Update Driver Software and then picked the usually worthless option Search automatically. To my surprise it downloaded a new driver that I never had before. The Texas Instruments 1394 OHCI Compliant Host Controller. The specific Unibrain drivers that came with my SIIG card never worked with the Flex at all. I cant wait to see if it works with the actual TI drivers.
