WHQL Certification Guide with HLK - From HLK setup to Microsoft submission — step-by-step

Microsoft's HLK docs tell you what to install. They don't explain why your Controller-Client connection silently breaks, why your machine pool gets stuck on NotReady, or which tests actually matter for certification. This 27-page guide covers the full process — with real screenshots, exact hardware specs, and the fixes for the issues Microsoft's docs skip. Free — get it via email.

We’re releasing our internal Gaming MCU Database. Should we expand to audio devices next?

We're working on a free Gaming Peripherals MCU Database here's why we built it.

Chipset selection for gaming mice and keyboards is surprisingly non-trivial. The same MCU category (ARM Cortex-M4, BLE 5.x) can mean wildly different polling rate support, USB architecture, power budget, and security capabilities depending on the vendor and specific series.

We've been maintaining an internal reference at Developex for years every time we started a new gaming peripheral project, the first question was always "what MCUs are we comparing?" This spreadsheet was the answer.
