Changes made
Adds support for the Logitech ASTRO A50 Gen 5 base station (USB
046d:0b1c).The base station uses a vendor-specific HID protocol (report ID
0x02on usage page0xff32,interface 8) — not HID++ and not the Centurion / report-
0x51protocol used by the A50 X.It was reverse-engineered from USB captures.
Capabilities (all verified on real hardware):
CMD 0x06)CMD 0x0a)CMD 0x09)CMD 0x0f)CMD 0x0d) — 10 bands, gain ±6 dB, Q 0.031–7.969CMD 0x14) — the A50 has 4 levels; HeadsetControl's 0/1/2(off/low/high) maps to A50 Off / Night / Tournament
New header-only device
lib/devices/logitech_astro_a50.hpp, registered inlib/device_registry.cpp, README device table updated. clang-format-18 clean, unit tests pass.The A50 exposes further controls (master volume, mic EQ, broadcast/stream mix, device state) that
don't map to any existing HeadsetControl capability — documented in
docs/ASTRO_A50_EXTRA_FEATURES.mdand intentionally left out of this PR (they'd need new corecapabilities; happy to contribute upstream if you're open to it). A companion GUI
(https://github.com/lluiseduardo-silva/HeadsetControlA50Gui) implements them meanwhile.
