Linus Tech Tips
$h!t Manufacturers Say
Some MSI motherboards have a USB port that is marketed (and explicitly labeled) as VR Ready. I haven't seen much documentation around what it actually does, except for marketing claims of a better connector, controller, and power delivery.
Compare USB 3.1 Gen 1 Port with MSI VR Ready USB Ports
Test on Valve Index and Oculus Quest as best and worst headsets
Latency
Is the polling rate actually faster?
Can you further overclock the VR Ready polling rate?
Can you overclock polling rate of VR on USB 3.1 Gen 1 and get same or better benefits?
Interference
Overall glitchiness / signal loss comparison
Power
Can you have a longer cord without signal loss using VR Ready than USB 3.1 Gen 1?
More reliable power?
Not sure how to test this one outside of maybe less glitchiness from power fluctuations.

Loading Your Entire OS into RAM
I know there have been videos around this before, but I'd love to see a video comparing performance with some of the Linux distro's that run entirely in RAM versus normal distro's.

Should you even care what USB port you connect to?
USB 2.0 v SS v SS 10
USB 2.0 - 480 Mbps
USB 3.0 / USB 3.1 Gen 1 / Super Speed - 5 Gbps
USB 3.1 Gen 2 / Super Speed+ / Super Speed 10 - 10 Gbps
Use Data Transfer speeds as Baseline / Control

Testing both with device connected through an otherwise empty USB Hub
Testing both with device connected through a usual gaming setup (mouse, keyboard, controller)
Testing both with device connected through a Streamer setup USB Hub (mouse, keyboard, controller, web cam, mic, headset, Stream Deck, ...)
Testing both with fully loaded USB Hubs and active file transfers from multiple inputs (artificial max load test)
Does Windows v Mac v Linux matter with USB handling?
Any significant difference in MOBO ports v front ports?
