when I debug a 1394B image device driver on windows 7 x64,
I found the result of REQUEST_GET_SPEED_BETWEEN_DEVICES requesting incorrect
sometimes, I have two controller, one 1394B (TI's PCIE chip), one is 1394A,
my image device run at S800, and connected on 1394B port. I want to get the
speed between device and host is 8 (S800), but sometimes I got 4 when I power
on my device with cable had connected.

Is there a bug of windows 7 1394 bus stack? thanks for any helps.
