Hello, I have a Studiologic Numa which connects via USB. For some reason when I connect the USB cable it powers on the keyboard but mac does not recognize it at all, and Audio Midi Setup is useless when I ask it to rescan midi. This is a brand new macbook pro running Snow Leopard. Oddly enough, it works fine with my old macbook running Leopard. As far as I know my USB port works fine, as I've tried with both ports and they seem to work well with my external hard drives. I have also tried to change the USB cable to no avail Any ideas?
