@RehabMan Thank you for the info. I was able to figure it out and every port is working great. I do have another question about your guide. You give an example of composite ports - where one port can be both HSx and SSx. Are these composite ports considered one port or two? I'm asking because when I use the IORegistryExplorer, I plug my 3.0 hub in and the SSx port turns green, but the same HSx port turns green at the same time. Does this mean that this is considered one port? I have other ports that if I plug in a 3.0 hub the SSx turns green, but if I plug the 2.0 usb into the same slot only the HSx turns green. In this situation, it makes sense to have two different ports. Any thoughts?
USB3 hubs activate on both the USB3 and USB2 pins, which is why you notice they light up both an HSxx and SSxx port.
It is why a USB3 hub makes a great device for port discovery.
A USB2 only device, of course, will only activate on the HSxx, just as a normal USB3 device will activate only on SSxx.
