Audiobox usb interface won't mount on MacBook Air

Question

PreSonus AudioBox USB (2in/4out) when attached to either USB on mid 2013 MacBook Air 11, won't show up in garage band, garage band preferences, apple audio system preferences, apple midi system preferences or even in the 'about this mac' system report.  The device is totally unrecognized and supposed to be totally compliant plug and play.  I'm runnin OS 10.9.1 with all updates.  The AudioBox interface shows red power light and a light on the 48V phantom power button.  All cables are good, Microphone functions and MacBook air is connected to a power supply.  (Macbook, condenser microphone, AudioBox and all cables are new.)  Any experience with this out there?

Answer 1

Yes, Id return it and either:
get the Roland UA-22 Duo-Capture EX
or the Focusrite Scarlett 2i2 USB
WHAT mic?
The best idea is to drop that noisy and hissy squawk box and get a ZOOM H6 which has USB interface with MORE options, LESS noise, and far easier to use
phantom power from the H6 is from 4 AA batts, and not via USB.    (have and use same myself) with these Mics:
The unit youre using is getting 48V phantom via USB, which depending on the Mic, often stinks.
