1394 device stop after reboot

I have a DV camera running through an optical fiber 1394
extender. Without the extender everything works fine.
With the extender, I get this message from the device
manager after rebooting: "device cannot start...". If I
unplug the device and plug it back it in, it starts
working. Also, if I use the device manager to disable
the device and re-enable it, it starts working.

What could the problem be? I've already installed hotfix
Q329256, "Inconsistent gap count can cause 1394 devices
to not enumerate." Which *did* resolve a problem I had
with the DV camera in general, but has not solved the
problem with the fiber optic extender in place.

Help!

Thanks,
Matt
