I had my Oculus replaced for black screen issue just received the new one today and have the same issue, gutted!
Why is it that difficult to provide the current drawn from the devices sensor/HMD? If they are in the limits specified by USB standard I do have something in my hands to get either back to my motherboard or USB card vendor.

If you're that hugely stressed over the current drawn by them, why don't you measure it? Shouldn't take anything more than a short USB extension and a cheap multimeter, cut it open and measure the current through the +5v wire.
This should work as well?

Would be suprised if that wasn't already tested by somebody.

HMD + USB3 repeater reads 0.31-0.41A (bounced around). Two sensors, a USB3 hub and a USB3 repeater read 0.61A. This is while in operation.
That means around 0.9A for three sensors + 0.4A for the HMD.
Is the USB specication meant per port or per controller? If every port can deliver 0.9A each, this should be fine, but if the 0.9A are shared between all ports of the same controller that could be a problem for some setups...
