Here is a HUGE problem alot of macbook owners are having with the whole
macbook line (pro included). If we plug in a usb audio device like
Serato scratch live (standard software in the dj world) or ProTools
M-Box, (again a standard in the music industry), We get usb dropouts
when we touch the keyboard or trackpad after it sits for more than 10
seconds (This means we lose connection to the box for a second and the
audio cuts out). This is because on the new line of macbooks they have
routed the keyboard and mouse through the usb port as you can see in
the system profiler. All the tests that I and other people have done
show that after about 10 seconds of no use on the keyboard and trackpad
they actually either go into a standby mode or go to sleep and then
when you go to use it, it wakes up and draws enough power and/or data
from the usb port to cause the audio interface to drop out for a
second. Does anyone know a way or have any suggestions on how to keep
the keyboard and trackpad on and not cause it to go to sleep every 10
seconds. I would expect better quality out of a $2500 laptop that
claims to be great for audio products and alot of people who own them
can't even use one of the usb ports for audio interfaces which really sucks. Never had this problem with any of the ibook or powerbook lines.
Apple, Someone, Please help, the audio community is begging for an os
update that keeps the keyboard/trackpad on.
Here are links to Serato's site and pro tools site showing this as a known issue:
