Valve’s Steam Link app for Meta Quest gained initial USB streaming support in the 2.17.8 public beta, letting users stream PC VR over a wired USB‑C connection after joining multiple beta channels.
Steam Link 2.17.8 public beta introduces initial USB streaming support for Quest headsets.
To use wired streaming you must join three betas: Steam Link public beta on Quest, SteamVR beta on PC, and the Steam Client Beta.
Valve hasn’t specified a required cable, but Meta’s guidance (USB 3.0+, ~5 meters or longer) is the reasonable recommendation.
# What changed Valve released Steam Link 2.17.8 as a public beta for Meta Quest headsets, adding initial support for streaming PC VR over a wired USB‑C connection. The update is distributed through the Horizon Store public beta channel for the Steam Link app on Quest and requires opting into two beta branches on the PC side as well.
# Why this matters Wired USB streaming gives an alternative to wireless PC VR streaming. It can reduce reliance on Wi‑Fi, remove wireless interference, and provide a more consistent link between the PC and headset. The update also includes some non‑USB fixes: reduced loading spinner flicker at low frame rates, corrected framerate display issues in SteamVR Settings, and unspecified latency improvements.
# How to enable wired USB streaming
# Cable guidance and practical notes
# Performance and context This wired option arrives alongside other recent streaming developments in the Quest ecosystem. Meta recently pushed a Quest 3 update that raises experimental refresh rates up to 240 Hz, and Virtual Desktop was updated to support up to 144 FPS over PC wireless streaming on Quest 3. Valve's wired Steam Link option provides a different path focused on direct USB connectivity rather than optimizing wireless throughput.
# Minimum PC requirements (as listed for Steam Link)
# Bottom line If you stream PC VR to a Quest headset, the Steam Link 2.17.8 public beta gives you a new wired‑USB option to try. Expect to join multiple beta channels to enable the feature and to use a USB 3.0+ data cable of sufficient length. Early adopters should watch for discovery quirks that may require an initial Wi‑Fi connection before the app switches to USB.

The supply of original virtual reality games has slowed to a dribble, and just as with Valve’s last hardware launch, the Steam Frame arrives covered in bumps and scrapes from a fight with the worst components shortage
