[...] Check it out! While looking through the blogosphere we stumbled on an interesting post today.Here’s a quick excerptI may be the last person to notice this for all I know, but I just plugged my FireWire-based Focusrite Saffire into a MacBook Pro 17″ and was treated to a blinking light show. The solution? Don’t use bus power; plug in the Saffire’s … [...]

I have a newish MBP (about 5 months old) and it wouldnt bus power my RME FF400. I contacted RME and they said the mac had lowered the bus power output, and actually replaced my FF400 with a brand new one at no cost.

My M-Audio Firewire 410 interface works fine off of buss power. However in Japan - where the AC is 100 volts- it didn’t work at all. Fortunately the studio had 117Volt power as well. This made all devices happy…..

went thru this months ago with my MBP 2.16GHz and
my Saffire and Fire Boxes and Firepod…

huge bummer having to engage the wallwart.

what i’ve heard is this: that Focusrite will upgrade your Saffire to be compatable with the MBPs if you send it back to them.

(i haven’t had a time window to send my Saffire back however..)

i believe we’re SOL with the Presonus, though..

also, though i haven’t really tested this, the boxes on;y need the extra power to BOOT, you can
unplug the power after they’re connected to firewire and booted..

I’m not sure if this adds or detracts from the conversation, but I ran into similar issues with my external USB drive and my 2nd gen 15″ MacBook Pro.

After I upgraded to 10.4.10 my USB drive just wouldn’t mount any longer. I took it in and the guy at the Genius Bar couldn’t figure it out. The drive popped up on every other machine we tried. Finally, we rolled back the OS to 10.4.9 and the drive mounted just fine.

I wonder, is everyone who is having problems with their audio devices running 10.4.10?

Even the previous MBP had this problem. I personally own the Focusrite Saffire and it works well on a first-gen black MacBook (Core Duo 1GHz). The solution Focusrite posted is the same as the Presonus Firebox. Apple limiting the power of the FireWire bus is a bad move IMHO.

the firebox has new osx firmware but only fixes a 96k issue…. buss power is still not with out the AC jump
