I bought a powered USB 3.0 hub for my mac yesterday. https://www.bestbuy.com/site/insignia-4-port-usb-3-0-hub-black/5631038.p?skuId=5631038 I wanted a simple way to plug in my audio interface, helix, and Akai controller. It works but Ableton keeps dropping the connection after a brief period. The audio interface seems pretty stable. Anyway - ideas? What's the trick to making these things work?
