Following Virtual Desktop's implementation of the feature, the latest Public Beta release for Valve's Steam Link on Quest adds support for wired USB PC streaming.

Meta Horizon OS 2.5 and later includes Android USB networking (NCM) support, meaning that apps can request a direct network link to a connected host computer over USB after the user approves the system-wide permission required to enable the feature.

In the case of Steam Link, this works by simply plugging a data-capable USB-C cable into the headset after launching the app. An active USB connection is currently indicated by a cycling Wi-Fi signal on the SteamVR dock.
