[DM-MUG] XServe G5 Port Issues

[Chris Van Cleve]

I'm tossing this out there to see if anyone has any guesses or 
suggestions. I have an XServe G5 that recently developed a problem:

None of it's ports work. Plug anything into any of the USB or FireWire 
ports, and it doesn't not work/mount. Using a USB keyboard, I can press 
Command-S to enter single user mode and all is well. If it boots to the 
GUI, the keyboard does not function. Same goes with the mouse. USB and 
FireWire drives do not mount.

Looking in System profiler, it states there is an Unknown Device on the 
FireWire bus, even though there is no external devices attached.

Thanks,

Chris
