Disable Usb Energy Saving Mode - Native Instruments Audio 2 DJ Operation Manual

Due to the current USB configuration 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 qualified 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 first; 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.

These USB port recommenda-
tions are specific to USB audio
devices only. USB keyboard and control
surface products do not have a recom-
mended USB port at this time.
