Hi, long shot sice FW 400 works, but...
Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive.
3. leave it for 10 minutes.
4. Connect back up and reboot.

I didn't try, or need, either suggestion as I ran TechTool Pro 6 to see what it reported and when it reported that I had FW functioning at 800Mbps I tried my FW800 port again and it "magically" was functioning again.
Thanks for the ideas for when TechTool Pro doesn't resurect my FW ports.
