Default Firewire Bus Power

Hi.


I've been using my Echo AudioFire12 for years with my Mac Pro, but now
I'm using it in the field with my MacBook (no-pro).


The AF 12 is (AC) self powered yet the MacBook automatically sends it
bus power, thusly running hotter and the fan never stops.


If I plug in a 6 pin FW cable to the MacBook and leave the other end
un-attached the fan never turns on. When I plug in the AF 12, the fan
starts up (within a few minutes).


It there an adapter cable or a mod that can be done to the AF12 so it
doesn't "ask" for bus power? Or is there a way to disable Firewire bus
power on the Mac (10.6.5)


Any suggestions?


Thanks!
Erik

There is/was actually an inline adapter that does what you want, but I could
not spot it in a casual search.

Found it. Bus power isolator.
