I suggest if at all possible try the camera on another computer with Firewire. If the camera is also not recognised on another system, then usually the little Firewire chip in the camera has been destroyed by ESD (Electrostatic Discharge). This happens quite a bit with Firewire cameras if the connection is made to the computer whilst the camera is being run from the mains with a power pack.
If another system recognises the camera OK, then the Firewire installation in your computer needs further diagnosis. But considering the number of Firewire failures in cameras we get to repair at my work, I'd check that first if possible, to save a lot of fruitless faultfinding.
