I have been diagnosing this problem and it seems to be that the two systems (usb and firewire) are competing for the same IRQs when the system starts. Indeed, in dmesg I see that the usb controller (2 ports) is correctly recognised but then seems to be overrided by the firewire unit which loads next.

I have fished around in log files and in the Info and control centres and can see information (e.g. the firewire adaptor is registered correctly as a PCI device) but am not sure how I can change the configuration (the IRQ?) so that both adaptors work.

Any tips would be a great help.
