OS - Win 7/64 latest notfixes etc, intel chipset, TI FW chip.
Just installed the UFX fo firewire as that it what I will be using it with.
Afterward installed the USB driver as well for flash updates, though it it not intended to leave it connected via USB.

Anyway if both the USB and FW cables are conncted get a BSOD dring windows boot.

This is with latest firmware, and latest usb and fw drivers. FW was installed first, this happened in the reboots following adding the USB driver which was done while the FW cable was still plugged in.
It would appear that the USB driver didnt actually install properly as windows tried to install it again after booted with the FW cable.

Not a biggy as it doesnt appear to affect normal operation, however still suggest there is something messy in either or both of the drivers - which allways translates to me being nervous about it crashing with loud screecheds etc., but please add it to your bug tracker for the driver sets.
