Firewire 800/400 Problems Options

[djrucksack]

Hi there.

I've got problems trying to make my firewire devices function to their full capablility.

I have a OWC Mercury Elite Pro Al 250Gb Triple interface external hard disk (what a mouthful!) connected to my powerbook G4 1.5Ghz via a firewire 800 cable to the onboard firewire 800 slot, and it works fine, running at 800 Mb/s.

BUT, I've also got an M-Audio Projectmix which connects with a firewire 400 cable. I've just bought a PCMCIA firewire adapter so that the hard disk and the Projectmix can have their own separate bus, but when I plug the Projectmix in the speed of the Hard disk connection drops to 400Mb/s.

I can't understand why, when they're connected on different buses.

(The whole reason why I bought the PCMCIA Firewire card was to get around this problem!)

Please help!!

Thanks.

I'm not sure at all if the order in the profiler is relevant as for a priority order… I doubt it.

If inserting the card only makes the speed dive down low to crawl, I think you have a suspect It's stupid it's so difficult to know exactly what is inside it as it's not this way we'll know if it can be firmware upgraded…

There must be some Terminal commands to list peripherals but it's beyond my humble knowledge…

On the tricks side there may be some things to try like find which PCMCIA card has the same black plastic part and see if it has updaters and try them but it trial/error/eventually destruction… Now we are sure of one thing, it interferes in a way it shouldn't, so it is not fully compatible with your laptop/OS.
