tl;dr; Connect everything first, then power on S5. Or use any USB hub between Mac and S5.
Update: Better workaround in my next post in this thread.
I've upgraded my MacBook Pro to new 2016 model with USB-C and I have issues with connecting it.
Obviously I have to use USB-C to USB-A adapter. I checked two Apple USB adapters and adapter of another manufacturer that I bought in local IT store. I also checked a few USB-A to USB-B cables, including the one NI included with S5. All have the same issue, so I don't suspect cables to be a culpirt.
The issue is that after I connect everything (MacBook <> USB-C to USB <> USB-A to USB-B <> S5) and when S5 is turned on – it doesn't connect to Mac. It is not detected by MacBook at all (the device is not detected on USB bus at all, no warnings from kernel or in system log, etc.).
However, if I connect it while S5 is off and then turn it on – it connects and works perfectly.
On the other hand, if I disconnect USB-C adapter from mac and reconnect it – S5 starts blinking. If I disconnect USB-A to USB-B cable from either S5 or USB-C adapter (so the adapter is still plugged to mac) and reconnect it – it connects well.
Also, using any USB hub in between solves the issue (checked cheaap USB-2.0 hub and USB3.1 hub that I have in LCD display), both were connected with same adapters.
I've recorded the video showing how it looks like so NI tech team can have a better understanding of an issue I experience: https://www.youtube.com/watch?v=mLDA6Fqk-9s
I'm software engineer, so if Traktor team requires more debugging on the issue on my side I can help.
