I was hoping I can find some updated information. I have a late 2013 (bought April 2014) MacBook Pro 15" retina display. I am using a kontrol S4 mk2 and have recently added an F1. I normally have the S4 connected to 1 USB port and an external hard drive (Western Digital my passport for Mac USB 3.0) connected to the other. I know I need a powered usb hub, but is there a recommended one to use? I do know that the S4 needs to be connected to the computer, but I use a different audio interface (MOTU 828) connected by thunderbolt. So my questions are...
1. What's the best powered usb hub to use? Should I get a 3.0 hub?
2. Since I am using a different audio interface connected by thunderbolt, is it still necessary to keep the S4 plugged directly to the computer?
