Firewire not recognised

I've just bought a 3.5" Firewire/USB Combo enclosure which connects up by USB fine but when I try to use the Firewire connection it doesn't appear to register. When I connect the Firewire cable I hear an audible notification that this has happened but nothing else. The drive does not show up in either My Computer or Windows Explorer.

If I look in "System>Hardware>device Manager" I see the Following:
Under "Disk Drives" Prolific PL3507 Combo Device (1394-ATAPI rev 1.10) IEEE 1394 SBP2 Device. This has an exclamation mark in a yellow circle.

Further down I see:
IEEE 1394 Bus Host Controllers
Texas Instruments OHCI Compliant IEEE 1394 Host Controller
and Below this under Network Adapters:
IEEE 1394 Net Adapter.
Both of which are reported as working.

I have tried uninstalling all of these and then reinstalling but with no effect.

Any ideas anybody?

 

I would disable the net adapter part, who uses firewire as an internet connection?

 

I've disabled the Net Adapter but the Firewire Enclosure is still not recognised despite still getting the audible notification that something has been connected.

 

Is this onboard firewire, if so what's the make and model of the computer?

Or is it a pci card or even an adapter(pcmia) for a laptop?

What's the OS and service pack?

 

By chance are you trying to connect firewire while usb is connected?

 

The Computer I am using is an Advent 7006, 1.8 MHz running Windows XP Home with up-to-date service packs. The Firewire is onboard. The Firewire is not connected to a USB port (I understand this is not possible) and the Firewire is not connected at the same time as the USB cable.

 

The computer is an Advent 7006 Laptop with a 1.8 MHz Processor, running Windows XP Home with the most up-to-date Service Pack and the Firewire is on-board. The Firewire is not connected to a USB Port - this is not possibleI am told! Also I am not connecting the Firewire while the USB is connected.

 

about the only thing left would be to check with another cable and/or another devise

or check the cable and drive on another computer
