So what is the list of things that the Headsets usb uses? Audi/Powering Headset/ Data for Touch controller, is that it? Doesn't this seem like a lot of thing to use for just one usb cable or is there even more?
The Rift has an internal USB 3.0 hub controller, Cypress CYUSB3304, which is divided into a USB 3.0 and USB 2.0 part.
" For those curious here is the block diagram of the Cypress CYUSB3304 chip. You can see that the USB 2.0 and 3.0 are completely segregated, so USB 3.0 will not be used unless there was a USB 3.0 device inside the Rift connected to it. "
The USB hub is internally connected to the Rift audio chip CMedia CM119BN and the ST Microelectronics STM32F072VB ARM Cortex-M0 which is processing data from the Bosch Sensortec BMI055 6-axis Inertial Sensor to send to the PC and controlling the constellation LED's.
There is no need for USB 3.0 for the headset at this time as the data being sent through the bus is not large.
(The sensors will connect at USB 3.0.)
This is also the reason that this internal controller (and then the USB "Rift" device) is showing up as "USB2.0" hub and connected to USB2.0 in Oculus Home. (Respective in my case this can often jump around. Before the Win 10 Creator's update it was mostly shown as connected to USB3.0, now however it shows as USB2.0 which technically should be correct since the USB3.0 part is indeed not used.
That being said, I THINK that it being connected to an actual, physical USB3.0 port means that it *CAN* possibly draw more power now from a hardware point of view.

Interesting. I've been scouring postings to decide whether it's better to put my headset or 3rd sensor on my USB3.1 Connection. I only have three (USB3.n) sensors: 1x(USB3.1) 2x(USB3.0) 6x(USB2.0) So, there's no issue with the hub in the headset routing the touch control at USB 2.0?
No reason not to try, certainly. When my headset was plugged into 2.0, though, I kept having the sound cut out. If what flexy said is correct, then that would have been a power draw issue instead of a bandwidth issue.
