SteamOS 3.8.25 beta adds Steam Controller support and fixes hardware-related bugs

The SteamOS 3.8.25 beta update introduces a new HID driver for the Steam Controller, allowing it to function as a controller without requiring the Steam client to be running. This update also addresses several hardware-specific issues, including improved battery charging indicators for devices that exceed the charger's power output, and preliminary support for the Steam Frame wireless adapter. Additionally, the update resolves a bug where HDMI hot-plugging caused system lockups in desktop mode and fixes an issue where TV displays would show the internal boot logo before engaging game mode, which previously caused unnecessary delays and flashing. The update also includes improved support for third-party handhelds, such as the MSI Claw and OneXPlayer, and adds an option for low-latency audio codecs for Bluetooth devices. In a separate security advisory, Valve confirmed that a cyberattack on CEVA Logistics, a third-party shipping partner, resulted in the potential compromise of personal information for European customers who ordered Steam hardware between July 29 and August 1, 2026. Affected data includes names, addresses, phone numbers, email addresses, and order details.
