Hi there, I bought a Total Computer DJ in a Box and until now, i had used it on a macmini. Now I installed the Tracktor software on a macbookair and the total control mixer is not working. I tried to connect this direct on the only USB port on my notebook, but the lights on mixer not turn on and it don't control nothing on software. The only signal that is connected, is that the MIDI icon on software screen blinks when I push any button on the mixer. I tried it too connecting on a belkin powered USB hub, but had the same problem. I read on support page, a document about the issue on USB mac that has to be not shared. But as I researched on web, The Macbook air's USB BUS TREE, has some internal device connect, turning it impossible to connect anything alone. All USB BUS was shared.
So, how can I used this equipment with my macbook air? As I know, this equipment is made to be portable as apple's notebook.
