The crystal case comes with two USB ports and a Firewire port and two leads - and the plugs match the sockets on my case and the Belkin card.
I eventually resolved it by uninstalling the device, plugging it back into the Belkin card, installing it (and it was still unreliable). Thereafter uninstalled it whilst still attached to Belkin card and then booted it up fot a plug n' play install in lieu of the mouse (which is back in its Belkin slot).
What a rigmarole. However it seems to be behaving itself now (at least at the moment). Couldn't recommend it to anyone, as the HD runs continually, the outer casing gets hot (which means the HD must be red-hot) and the transformer gets too hot to handle also. I daresay it's chewing up 80 to 100 watts just on standby.
