SteamOS Beta Adds Gamepad Support for MSI Claw 8 and Ayaneo

Valve’s SteamOS 3.8.25 beta doesn’t just fix bugs — it officially starts welcoming new hardware. Tucked into the ‘Non-Valve Devices’ section are initial gamepad hooks for the MSI Claw 8 EX AI+, Ayaneo’s Snapdragon-powered Pocket S2, and the Konkr Fit, a recent Windows handheld from one of Ayaneo’s sub-brands. For anyone who has watched Valve’s Linux distro slowly inch beyond the Steam Deck, this patch note is more consequential than a dozen bug fixes.

The update also refines gamepad support for the OneXPlayer Apex and ships new Steam Machine firmware that fixes a rare sleep/wake CPU performance bug — the latest in a run of SteamOS beta features like HDR remote play for the Deck OLED. But the non-Valve additions are the real story: Valve is treating third-party handhelds as first-class citizens, not an afterthought.

The Input Layer Is the Hard Part of Handheld Linux

SteamOS’s input stack is why the Steam Deck feels like a console instead of a PC. Getting that same experience on the MSI Claw 8 or Konkr Fit means recognizing each device’s controller hardware — not just the face buttons, but Hall-effect triggers, TMR joysticks, and whatever vendor-specific behavior ships alongside them. ‘Initial’ is Valve-speak for ‘we’re not done yet,’ but it’s also the essential first layer. No gamepad driver, no functional SteamOS install; this is the prerequisite everything else depends on.

The Pocket S2’s presence is the eyebrow-raiser. It’s Android-first and Snapdragon-powered, not an x86 Windows machine, so it doesn’t fit the usual ‘install SteamOS on this PC handheld’ template. Its inclusion suggests Valve is cataloging the entire portable ecosystem, not just the devices that can run its full OS. That breadth is what a serious third-party handheld platform looks like.

SteamOS Is No Longer Deck-Only — But Patience Still Required

None of this means you should wipe Windows off a Claw 8 and go all-in on SteamOS this weekend. ‘Initial’ gamepad support is one layer of a many-layered problem: audio routing, suspend/resume, TDP controls, and display management still need to be ported before Valve’s OS is a daily driver on these machines. What this update does is shift the calculus for anyone choosing between a Steam Deck and a Windows handheld. The console-like experience that previously belonged almost exclusively to the Deck is now visibly being engineered for the wider market — the SteamOS-everywhere future we’ve been tracking.

RAM prices are punishing every new handheld right now, and no software update fixes that. But Valve is at least removing the OS as an excuse to stick with Windows. The takeaway: SteamOS’s third-party era is officially underway, and the hardware you buy from here on will have more Linux options than any previous generation. That’s a win for every handheld owner, even if you’re staying on Deck.
