Why is my iMac DV so damn picky considering the Firewire-port?
Sometimes it sees equipment connected to the firewireport, but most of the times it doesn't. In the systemprofiler I get this information about the firewireport : fw756266,6f7464

This is not an easy to solve problem

I tried different cables
I zapped PRAM
I used Diskdoktor
I used techtool
I tried my powerbook on it using it as a targetdisk.
I cannot upgrade from 2.4 to 2.5 because my system(OS9.2) is too new???
I switched the firewiredrive on and off multiple times
I inserted a written disk into an external fw-cdrw to hopefully mount

I was having a problem with the fact that Toast Titanium would not recognize my CDRW, but the system did.

I removed Firewire Authoring Support and USB Authoring Support from my extension folder and now Toast Titanium recognizes it. There appears to be a problem with Apple's iTunes' or DiskBurner's extensions controlling the drive

G4 Mac desktop and OS 9.2.2.

also, if your firewire device came with its own firewire drivers (such is the case with lacie firewire drives - well used to be anyhoo), try removing the extra extensions. Your default system extensions have the full capability for supporting firewire devices. I had to troubleshoot a g4 video editing machine once and the culprit turned out to be the lacie extensions.

Oh and also i'm assuming the firewire device has its own power supply? powering off the bus does't always work.

A while back we had a thread going about FireWire hard drives, and it seems like the answer was either the device needs to be powered on before the computer is booted up, or if being powered on after the computer, it needs to be physically plugged in AFTER being turned on. In other words, leaving a device plugged in all the time, and then powering it on after the computer is already up and running doesn't work - in this case, you have to physically unplug the the cable, and then plug the cable in after the device is on. I would test this right now, but I'm booted off of my FireWire drive...

refer to post firewire harddrive for the previous discussion on difficulty with firewire hard drives. Hopefully this is the same problem!

The issue is not that Toast doesnt see the firewiredrive,
the issue is that the imac doesnt recognise its own ports.
Thats the reason I get the strange number in the system profiler.

if it were a toast problem, phew, i was lucky.
