For the following laptops the use of USB audio devices on the USB port closest to
the screen is not recommended:

There are 2 USB ports on the left side of the MacBook models listed above.
Due to the current USB configuration 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 qualified and is fully
supported.
11.3.5 Disable USB energy saving mode (Windows only)
If you are experiencing problems with the AUDIO 8 DJ causing crashes or performing
badly on a Windows machine, disable power management to the USB hubs first; in
Windows XP this option is switched 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.
