Oculus Explains How Room-Scale VR Taxes Your USB Ports

Oculus has elaborated on the kind of USB bandwidth their room-scale VR system relies on, but some would believe they are only embarrassing themselves. That is because HTC’s solution, Lighthouse, does a lot of the same with less hardware and bandwidth requirements. Here is an older article that goes into some of their differences.

Most home PC owners don’t really push their USB very hard. You might connect an HD webcam, but many devices (other than external storage) don’t have a very high bandwidth requirement. If you connect three Oculus sensorsآ—each sending and managing a ton of data locallyآ—you can run into problems when they try to send more data than the USB host controller can handle. That’s why we recommend only connecting two sensors in USB 3.0 mode to a single USB host controller and connecting the third sensor in USB 2.0 mode. That said, in our experience connecting two of three sensors to USB 3.0 and one to USB 2.0 works just fine. These guidelines are here to help you try other configurations or to potentially improve some USB issues with your particular computer setup.
