Technical Reference

Every layer of HIDMaestro from the C# SDK down to the kernel-side HID stack. Read the first five in order for the full picture.

• Architecture Overview: the stack diagram from SDK to driver, per-controller WUDFHost processes, and the three architecture groups.
• UMDF2 Driver Internals: driver.c, the IOCTL dispatch table, the device context, and the event-driven worker.
• XUSB Companion: how Xbox-family profiles get XInput without a kernel driver.
• SwDevice and PnP: device creation, container IDs, and the XInput slot-0 story.
• Shared Memory Protocol: the three sections per controller, the seqlock, and the named events.
• Cross-API Coverage: how DirectInput, XInput, SDL3/HIDAPI, the browser Gamepad API, and WGI are each satisfied.
• Multi-Controller: verified mixed-type operation and per-API ordering.
• Lifecycle and Teardown: create paths, removal ordering, and round-trip latencies by archetype.
• Driver Install and Signing: the embedded payload, certificate generation, and the idempotent install.
• Build and Release: the two-phase build and the release recipe.
• Testing and Verification: scripts/verify.py and the 46-scenario regression battery.
• References: authoritative sources for every load-bearing claim in these docs.
