We were a bit late when we discovered wireless USB had been a thing. Still, we managed to find one pair of emitter and receiver that also transmitted HDMI, power the "receiver" side with a battery, in a backpack, and hook it up with another power bank to an Oculus DK1.

Unexpectedly, battery time was never an issue. The WUSB chip in the receiver would overheat long before that and start throttling, leading to jittery head tracking.

Turned out, it was a widespread issue with that WUSB chip.
