FireWire bus error
FireWire devices which work fine on most Macs, do not mount on a G5.
Applejack reports this error:
Firewire (OHCI) Apple ID 52PCI: no valid self ID's for more than 3 mins after bus reset
I have reset PRAM and NVRAM. Also a SMC reset by leaving the G5 power unplugged and holding power-on for 5 secs.
Does this indicate a hardware or software problem?
This is not a rare problem, because it has been asked many times before but I have not seen any explanation or solution.
