AUDIO 2 DJ – 39

Due to the current USB conguration of the MacBook Pro under OS X, use of USB audio

devices is supported on the left-hand USB ports only (the port or ports next to the power

adapter cable). Use of audio devices on the right-hand USB port is not advised because it

may cause audio interrupts and/or dropped samples. However, the use of an iLok dongle

on the right-hand port has been qualied and is fully supported.

Due to the current USB conguration of the MacBook under OS X, the use of USB audio

devices is supported on the front USB port only (the port farthest away from the screen).

Use of audio devices on the rear USB port is not recommended, because it may cause

audio interrupts and/or dropped samples. However, the use of an iLok dongle on the rear

port has been qualied and is fully supported.

9.3.5 Disable USB Energy Saving Mode (Windows only)

If the AUDIO 2 DJ is causing crashes or performing badly on a Windows machine, disable

power management to the USB hubs rst; XP turns this on by default.

To disable power management for USB hubs, open the device manager (Control Panel

> System > Hardware) and right-click a USB hub to bring up its properties. On the

power management page, uncheck all boxes. Repeat for each hub and reboot.

surface products do not have a recom-

mended USB port at this time.
