The original v2 prototype and original p4k only used USB power.
We know now that the v2 was only running Dual usb 2.
So with the 8kX now running Usb 3 main with a Usb 2 backup for power. It should be good. Though as we know there is an issue with the usb 3 driver in the headset it possible it maybe doing wonky things. Especially as some have found you can run it just on the usb 3 without the usb 2 power.
