So this morning I plug in the USB for my M-Audio into MP.A window opens interface last used not available M-Audio is so I go ahead and set up a guitar track can see green in track but nor master the top one.So I close it and restart plug in all it shows is USB-CODEC that's the Berringer now it will not recognize M-Audio. I turned off GarageBand in iCloud nothing.Can anyone help?
