We’ve been dealing with USB for about two decades now, and to be honest, we’re not usually asking that much from it. Plug in an adapter, microphone or game controller, then keep it moving.
All of that changes, however, when it comes to virtual reality. plugging in a bunch of room scale sensors sends enough data through the ports to potentially overwhelm the 400MB/s capacity of the controller Oculus chip on your motherboard.As Oculus explains,
Oculus says you should probably get good results by using two USB 3.0 connections, plus one older USB 2.0 port if you need to go beyond two sensors to get some more mobility in your VR experiences. Because of this, the how room answer isn’t to simply plug in a hub and get more high-speed USB 3.0 ports, in fact, so go ahead and USB ports check out all of the posts Oculus to make sure everything is positioned and working correctly.The blog is currently helping gamers get through the setup process,
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,” Oculus explains. how room “If you connect three Oculus sensors each sending and managing a ton of data locally you can run into problems when they try to send more data than USB ports Oculus the USB host controller can handle.
which is more like 3.2Gbps (around 400MB/s) when accounting for how room overhead. And for USB 2.0, the total bandwidth is 480Mbps (60MB/s),With USB 3.0, the theoretical bandwidth per Oculus controller is 5Gbps (625MB/s), or around 308Mbps (around 36MB/s) after overhead is factored in.
So Oculus says it’s generally better to how room have a reliable lower-bandwidth USB 2.0 connection for your third sensor versus running three high-bandwidth USB 3.0 USB ports connections at the same time.Devices connected to the same controller in USB 2.0 mode don’t share bandwidth with USB 3.0 devices,
However, if you’re having trouble balancing the Rift’s room-scale sensors across multiple host controllers,You may have multiple USB host controllers on your motherboard. Oculus In the USB ports third how room and final blog post on the matter, one way to solve that is by purchasing a PCI-Express USB card. and Inateck SuperSpeed USB 3.0.Oculus said it’s how room had good luck Oculus with the HighPoint RocketU 1144d,USB ports Startech SuperSpeed USB 3.0,
