I have an M-Audio 4X4 midi interface that I've hooked up to an '09 Mac Pro 10.9.1.......and getting no response from it at all. Not even the USB indicator light.
I had been using it without problem on an old G5 [PPC]
I went to MAudio's site and downloaded the most recent drivers for the unit....[8. ??] but still nothing.
Tried it again on the G5 and its working.
Anyone have a suggestion on whats wrong here ?
Thanks for any help
