Really strange. Disconnect all peripherals and try the firewire port again.
Your issue appear when wireless, connected to the ethernet or both?
Another thing to try -
Disconnect all peripherals from your computer.
Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
Restart your computer when done.
Repair permissions after you reach the desktop-http://support.apple.com/kb/HT2963 and restart your computer. Firewire port work?
This is really unfortunate, but the problem has reoccurred. It happened last night, and I repaired disk again which fixed it. Literally minutes later it stopped working AGAIN, and repair disk didn't do anything this time. I also tried repairing disk permissions but that did nothing either. I've just contacted Focusrite with an email but I'm afraid I'll have to sell this now and try another interface... what could be causing this??? Any other ideas on how to fix this?
I think the problem is that the firewire port isn't even being recognized by the Mac at all... I opened system profiler and it says "no firewire ports found". Even if nothing is connected shouldn't there still be something there? I'm considering upgrading to 10.7 since I can for free, courtesy of my school, to see if it will fix it. Honestly I am so frustrated with this...
I turned off my Macbook and unplugged everything for 30 min, turned it back on and the Firewire port was showing up in system profiler again... then I tried plugging in the Saffire Pro24 DSP and nothing, Firewire port went back to being non-existent in system profiler..... wow.... this is... so dumb... -_______-
